Turntable Listening Experiment and Wrap-Up Tuesday, November 21, 2023

A few weeks ago, The Tracking Angle posted a YouTube video comparing two turntables, using the same arm, cartridge and phono preamp.

The two unit sounded surprisingly different to my ear, given the only change was the actual device holding and spinning the LP (assuming, of course, that when the arm was moved it was properly set up; given Michael Fremer was the one performing the test, it seems a good assumption).

But that gave me an idea. Since I had a few cartridges, turntables and preamps here, I thought I would perform the same experiment. I sourced the same LP from Japan, bought an A/D converter (the Focusrite Scarlett 2i2 4th Gen), and made seven recordings, with various combinations of Turntable, Phono Preamp and Cartridge. I also stripped the audio out of the Tracking Angle's YouTube video, for a total of nine recordings of the same track.

But rather than show what equipment was being compared, I took those nine completely blind and anonomized recordings and posted them to Mastodon, asking people to provide their rankings and impressions without knowing what was what.

Thanks

Before I provide the summary information, I wanted to thank the people who took the time to participate in the experiment. The recordings, all told, take about 55 minutes to listen to, and often people made multiple passes to decide on their rankings. Hopefully it was as fun for them as it was for me.

Caveat

As I indicated in the "toot", the various recordings were not level-matched. I did the best I could in the analog domain, but in general the output of the preamps were high enough that the Focusrite couldn't "drop" the level any lower. I didn't want to manipulate things in the digital domain, so I left it to listeners to level-match.

My own rankings were not included in the test, since there was no "real" way for me to listen blind...and I was well aware of all the telltale indications of what was what after doing all the recordings. I tried shuffling the playback order and making multiple passes that way, but I couldn't eliminate bias, so...

Results

Given the caveat above, these results don't necessarily correspond to my rankings. Rather, they're the average of the rankings provided by the participants. And there's no "right" or "wrong" answer!

With that in mind:

  1. Sample F, ranking 2.33 - Aesthetix Rhea Signature phono preamplifier, Bang & Olufsen Beogram 4000 linear-tracking turntable, Bang & Olufsen MMC20CL cartridge from 1981.

    A bit of a surprise, frankly! The Rhea is an all-tube phono preamplifier that's quite well regarded, and it was well matched with the vintage 1972 turntable and cartridge.

  2. Sample B, ranking 3.17 - Brinkmann Edison Mk II phono preamplifier, Brinkmann Taurus direct-drive turntable, Brinkmann 12.1 arm, Audio-Technica AT-ART1000 Moving Coil Cartridge.

    The Edison is a hybrid Tube/SS design, with a solid state initial gain stage and a tube output stage.

  3. Sample A, ranking 3.5 - Brinkmann Edison Mk II phono preamplifier, Bang & Olufsen Beogram 4000 linear-tracking turntable, MMC20CL cartridge from 1981.

  4. Sample H, ranking 3.66 - MoFi MasterPhono - Bang & Olufsen Beogram 4000 linear-tracking turntable, Bang & Olufsen MMC20CL cartridge from 1981.

    The MoFi is a recently released solid state Phono Preamp. This particular recording lowered the peak levels (gain) compared to sample C, featured later, but was otherwise identical.

  5. Sample G - ranking 4.43 - CH Precision P10 phono preamplifier, TechDAS AirForce III Premium turntable, SAT CF-12 tonearm, Lyra Atlas Lambda SL cartridge.

    This recording came from the YouTube video, and is the less expensive of the two Tracking Angle setups...at around $300K.

  6. Sample I - ranking 5 - Aesthetix Rhea Signature phono preamplifier, Bang & Olufsen Beogram 4000 linear-tracking turntable, Bang & Olufsen MMC20CL cartridge from 1981.

    A shock to me! Sample I is identical to the winner, Sample F - except it's uncompressed, whereas Sample F is encoded with high-bit-rate AAC. ¯_(ツ)_/¯

  7. Sample E - ranking 6.25 - MoFi MasterPhono - Bang & Olufsen Beogram 4000 linear-tracking turntable, Soundsmith SMMC20CL+ cartridge.

    The Soundsmith cartridge is a modern, drop-in replacement for the vintage MMC20CL, made by Peter Ledermann of Soundsmith. (It's one down from their top-of-the-line SMMC20CLV.)

  8. Sample C - ranking 6.6 - MoFi MasterPhono, Bang & Olufsen Beogram 4000 linear-tracking turntable, Bang & Olufsen MMC20CL cartridge from 1981.

    Identical to 6 save for the cartridge.

  9. Sample G - ranking 7.2 - CH Precision P10 phono preamplifier, OMA3 turntable, SAT CF-12 tonearm, Lyra Atlas Lambda SL cartridge.

    This recording came from the YouTube video, and is the more expensive of the two Tracking Angle setups...at around $600K.

I found these results extremely interesting. In general, people seemed to prefer the tube preamps to the solid state ones. Given the LP is cut quite hot, I'm guessing that there was a preference for the sound of the tubes at the margins, vs Solid State. The tube amps were all set to their lowest available gain levels for the high-output Moving Iron cartridges and appropriately for Moving Coil; the MasterPhono was set, using a test record, for the correct 0dB level at 1kHz.

The vintage Beogram turntable did remarkably well in the public rankings, despite its age, as did the vintage cartridge. In identical setups, the newer Soundsmith version ranked better...but it was close. Overall I thought all the B&O cartridges had a bit of a mid-bass boost, and, as mentioned above, are quite high output. Sample H was an attempt to keep the peak levels a bit lower and give things a tad more headroom.

Finally, the extremely expensive Tracking Angle combos didn't perform as well as expected with the pubic, despite their excellent reputations and reviewed performance. I'm not sure that means anything, since experts indicate they're some of the finest combinations of equipment ever made.

But, what it does show is that you don't necessarily need to spend hundreds of thousands of dollars to get a setup that you'll enjoy... and enjoyment, after all, is the point.

Happy Thanksgiving, everyone!

Plastic Fantastic Sunday, November 07, 2021

I'm sure it's clear from everything I write, but I am, as they say, an Old.

Part of that involves going through many technological transitions: computers; cars; TV; cable, satellite; cell phones; BBS systems; internet; touch-tone phones... I mean, it goes on and on.

Many of those are major advances; certainly, I wouldn't want to go back to the days before computing was ubiquitous. At least, I don't think I would. Probably.

Ch-ch-changes

Music has always been an important part of my life. The first thing I ever saved up to buy, in a serious way, was a decent stereo: a Sansui integrated amp, Thorens turntable, Nakamichi TX-2 tape deck and a pair of AVID 230 speakers. I think nearly all of two summers' wages went into this, and the rack to put it in. (Sadly, it was later all stolen out of my dorm room in college.)

Over the years, along with that equipment came a lot of music starting, of course, with LPs. (Embarrassingly, I think the first album I bought with my own earnings was the Jaws soundtrack. It's a great soundtrack, but geez...nerd.)

For the most part, over the years changes to "music storage" were motivated by either "convenience" (vinyl LPs weren't something you could play "portably"; CDs took up space; etc) or "quality" (much less common, but CDs were an attempt to be better and more robust than vinyl; basically all other attempts at improving quality have failed in the broad market -- people don't seem to care).

But at each point, something was lost in the transition. Leaving cassettes aside, the transition from vinyl to CDs basically lost the album art and liner notes. The move to digital lost the physical media entirely, so even the size-reduced "cover" was gone, tactile experience lost. And streaming has been, well, awful for artists and completely eliminated the whole idea of "owning" an album...you almost don't even care whether you've "selected" something...with no cost, there's no need to engage, research, or even think about it.

Sure, streaming service. Hey, iTunes. Just put on something I'd like. Whatever.

The Wayside

But, in that ubiquity, we've left so much behind.

The whole experience of music stores; talking with a proprietor whose tastes help you find new things (hi, long-ago-closed Tom's Tracks in Providence!; hey there, long-ago-closed Town and Campus in Plymouth!); flipping through bins of beautiful covers; reading Robert Christgau's haiku-like descriptions of music in his guide; trying to figure out what the hell he was trying to say.

And then, selecting—sometimes on instinct—and bringing it home. Committing real money...and being invested in what's going to happen. The experience of opening an album; coaxing the disc out of the sleeve; placing it on a turntable, cleaning it, carefully lining up the stylus with the lead-in groove and...with the descent...a soft pop...and, somehow, music, taking you on a journey.

Comprehension

I look at a CD and I kind of understand the deal with how it functions. You take waveform in the analog domain, where we all live. You sample that at a rate that basically works. You record the numbers. You burn the bits to a disc. It basically makes sense. It's a scheme I could have thought up.

Mono music is kind of the same. Waveform makes wiggles. You trace the wiggles on a disc. You play back the wiggles. I get it.

Stereo, though, I just don't know. 45-degree cuts? A single groove that somehow produces two channels? I mean, the music is literally right there. It's entirely visible with your eyes, and yet so mysterious. It's not something I would have thought of. Analog is a kind of crazy, weird thing.

There's some sort of magic going on.

Experience

Sure, there are limitations, as there are with everything. As "receivers" of the information we're profoundly limited.

We're also limited in attention, which has, at least in my case, gotten worse over the years. Albums, though, are something you can't really ignore, because in 17 minutes or so they demand your attention as you need to lift, flip, clean and start side 2.

It's an experience that has to be planned by the musicians. Sequencing. Time between tracks. The side break. The inner sleeve, gatefold, cover, type, art...all of it working together, encouraging attention, focus.

Focus

And I think that's part of it. Vinyl encourages—requires—attention. You have to be an active listener.

It can clearly sound just as good (or bad) as any other method of music storage and reproduction. I'm not going to make claims of some sort of sonic miracle that occurs when stylus hits groove. But I am going to say that everything, as a whole, is just so much more enjoyable.

Your own focus makes you hear things. And the trip the musicians planned for you takes you somewhere. They tell you a story. You just have to listen.

You have to focus.

It Came from the Basement

So, up from the basement came my old records. A turntable from years ago, restored and plugged in.

With the spinning, the vibration, the concentration, a broad smile. It's really good to have this music ritual back.

And amazing to discover what you can hear when you give yourself the time and space to focus.

I Like Batteries! Friday, August 07, 2020

I've probably mentioned on the blog before that I'm a big fan of electric cars.

Starting in 2013 with a first generation Tesla Model S P85, both Z and I have been powered by electrons, with two leased BMW i3s and we've now replaced the Tesla with a Porsche Taycan.

I was a guest on the I Like Batteries podcast, and like a little yapping dog who just won't shut up, I overstayed my welcome, so it was split into two parts. Part one went live today, and part two drops next week.

Enjoy! (That should probably end in a question mark, or be surrounded by scare quotes.)

Relax, Have a Homebrew! Monday, October 16, 2017

Off-topic alert!

Over the past few months, I've been enjoying brewing beer at home with a Pico Pro. No doubt purists scoff a bit at the automation involved during the mash and boil, but it's a relatively small part of the beer making process...and doing a true, temperature-controlled step mash without investing in an expensive setup (not to mention the space it would take up) is a huge win.

It's been a lot of fun.

The biggest challenges, and the place where a lot of brewers fall down, are in sanitizing and controlling fermentation: keeping things at the right temperature, consistently, so the yeast can work its magic efficiently without producing off flavors.

I can't help with sanitizing (you just have to do a better job!) but I can help with fermentation!

To that end, there's a great device called a TILT Hydrometer. The TILT drops into your fermentation vessel (which, in the case of a Pico Pro, is a small, 1.75L corny keg), and transmits both temperature and specific gravity via Bluetooth 4/BTLE. It's pretty cool, and by using TiltPi, along with a Raspberry Pi Zero-W to receive the bluetooth data and log it to a Google Sheet, it does all this automatically. You just peek at the sheet every so often to see how things are doing.

That all works great, but reviewing the data I realized I was having trouble controlling the temperature precisely using an external thermometer. Given the open source nature of TiltPi, and that fact that it was built with Node-RED, I thought, hey—I could use the temperature being transmitted by the TILT as a current measurement, and then use IFTTT and a few WeMo switches to exactly control both heating and cooling!

So, over a few hours in between doing SuperDuper! stuff, I learned Node-RED, figured out how TiltPi worked, added automatic temperature control, and found/fixed some TiltPi bugs at the same time. It works great!

I've provided the TILT people with my modifications to TiltPi, and hope they'll be integrating it into the official TiltPi release. Until then, here's how you can use it:

  • Set up TiltPi according to TILT's normal instructions.
  • Download and unzip this text file and open it in your favorite editor.
  • Open the TiltPi Node-RED editor. This should be here: http://tiltpi.local:1880.
  • Copy the contents of the text file to the clipboard.
  • Using the "hamburger" menu, select Import > Clipboard. Paste the copied contents into the box, and choose to import into a "New Flow". It'll be called "Main".
  • Switch to the old flow tab and delete it.
  • Click Deploy.

That's all the hard stuff. Next

  • Set up your IFTTT Webhooks service so you get a key.
  • Copy that key to the clipboard.
  • Open TiltPi's normal interface at the URL it sent you when it started up (usually http://tiltpi.local:1880/ui/#/0).
  • Using TiltPi's hamburger menu (so many hamburgers!), select "Logging".
  • Paste your key into the IFTTT key* field.

Then, set up your various color TILTs normally. You'll see a Target Temperature slider - that's configurable on a per-TILT basis and defaults to 70F: reasonably appropriate for ale fermentation.

The next step is to set up the heat and cool steps in IFTTT. (I assume you've already got your WeMo switches configured and WeMo is connected to your IFTTT account.)

  • Create a New Applet in IFTTT.
  • For the "This" clause, add a Webhooks service.
  • For the event name, use TILT-COLOR-temp-low, TILT-COLOR-temp-high, or TILT-COLOR-temp-just-right. depending on what you want to do.
  • For "That", add the appropriate WeMo switch action.

For example, let's say that I want to control a heater for a BLUE tilt. I'd add three Webhook applets:

If BLUE-temp-low then Blue WeMo Heater Switch on
If BLUE-temp-high then Blue WeMo Heater Switch off
If BLUE-temp-just-right then Blue WeMo Heater Switch off

If you want to both heat and cool, you'd add three more events (since you unfortunately can't add extra actions to an existing event):

If BLUE-temp-low then Blue WeMo Cooler Switch off
If BLUE-temp-high then Blue WeMo Cooler Switch on
If BLUE-temp-just-right then Blue WeMo Cooler Switch off

More events can be added for more TILTs, each with its own target temperature and WeMo switch(es).

If you don't have a cooling device, and it's warm where you put your keg, do what I do: put the keg in an insulated cooler bag (I have an old version of this bag) along with an ice pack. That way, when the heater goes off, the ice pack will act as a cooler.

I hope that helps some of you make better beer. Enjoy!

Note: this post was updated on 10/22 with a new version of the flow that works better with multiple TILTs, now that I have more than one.

Clicking away Friday, April 27, 2007

My friend Jonas Salling has started blogging again, and that's always a good thing.

He's got some recent posts up there as he tests the WiFi support for Clicker, and the results may surprise you!

Jonas is one of the hardest working developers out there, and he never settles for less than absolute excellence when releasing new stuff.

The long-in-development Clicker 3.5 is no exception, and it looks like it's getting really close to release. That's good news for all the fans of Clicker, since a great product is getting a lot better. And I'm sure he has many cool things in store moving forward as well.

Welcome back, Jonas -- looking forward to more posts!

Comfy sweater - marked down! Thursday, March 15, 2007

Some time ago, I switched from MarsEdit to ecto. Mostly, I did this because I liked writing posts with "real" formatting -- that is, using the RTF editing view that ecto offered.

At the time, I was only allowing myself 15 minutes per post, and the HTML I was using in MarsEdit simply got in the way of quickly reading the post for content. Too much translation, the Preview didn't really do it for me... and it didn't look like Brent was going to find much time to work on the program (understandable, given his success with NetNewsWire).

Given that set of issues, I switched. Not all upside (the HTML generated by the RTF translator was rather sub-optimal), but overall it worked for me.

With Daniel Jalkut's recent acquisition of MarsEdit (congratulations, Daniel!), and his flurry of activity improving the core and fixing bugs, I've decided to give it another shot. And to get around the readability problem, I'm giving Markdown a try.

I don't know why I didn't use Markdown before -- probably, I didn't want to learn yet another thing. Maybe I just wasn't aware of it. But I'm glad I've finally found it and taken the time to figure it out. Markdown's pretty easy: natural to read and write once you grasp the basics. JG and Aaron Swartz did a good job with the syntax: it's regular, logical, functional, readable.

And it's supported by Expression Engine, too.

So, three posts later, I'm sticking with it. Hopefully with these few changes I'll be able to find a bit more time to blog!

Happy New Year! Sunday, December 31, 2006

It’s hard to believe another year’s gone by, but dates rarely lie, and there it is - the 31st, soon to flip.

Rather than turn inward and reflect on events here, I’d like to turn outward and thank each and every reader; all those who took the time to send me mail - those who needed support, needed to vent, to compliment or complain; the kind people who provided comfort as we lost our dog Ketzl and who cheered the arrival of Taiko; the editors at Macworld who honored us again; the users who honor us every time they use or recommend a Shirt Pocket product; all friends, old and new.

To all of you: thank you, and a very Happy New Year to you and yours.

Blogrolling in our time… Wednesday, October 05, 2005

Looks like Rich Siegel, of BBEdit fame, has started blogging. And he’s ragging on bad drivers! Go Rich!

(And don’t miss the great Oktoberfest Special they’ve announced over at Bare Bones. $99 is an incredible bargain for the exceptionally well regarded editor… if you’re even remotely thinking about snagging a copy of BBEdit, now’s the time!)

NetNewsWire v2.0 Design Friday, June 03, 2005

Brent Simmons has just blogged a bit about the design of one feature in NetNewsWire 2.0on his blog. If you’ve been enjoying my posts about this, you’ll probably enjoy Brent’s, too!

Brent classifies himself as an Experimenter/Gatherer, which I usually am too, when actually doing the coding. When I’m doing the design, I try to experiment as much as possible on paper and roll in feedback, but get close to final and keep the tweakable elements to a minimum so as not to waste Bruce’s time.

That doesn’t always work out, as my Scheduling posts show…

How “unique”! Wednesday, April 27, 2005

So, what should you expect from this blog?

My plan is to write about a relatively eclectic set of topics. I’ve sketched out my first 30 posts or so, and they seem to be falling into the following broad catagories:

  • News about Shirt Pocket
  • Software design and development
  • Computing from a user’s perspective
  • Occasional stories about small company development, marketing and support
  • Consumer electronics and usability
  • Dogs and Degenerative Myelopathy
  • Gadgets I like
  • Movies & Music
  • The occasional random rant

No huge surprises there. I’m sure other things will creep in now and again, but for now, there you go.
