Whos got turntable performance measurements?

I can find technical measurements for so many things - but almost none for turntables. I'm talking about frequency response, signal to noise, channel separation, nonlinear distortions graphs...

Does anyone have any good sets of data? Occasionally, I can find a little here or there, but nothing really substantial.

What are you analog guys scared of???😀

I might be wrong here but I think frequency response, channel separation, etc. mostly relate to the cartridge/pre-amp and not to the turntable. All commercially sold TTs have main parameters listed (rumble, speed accuracy, etc.) in the manuals. So I am not sure what you are looking for.:scratch2:

I asked the owner of Teres audio for rumble specs on his TTs. His answer was, "It's not about the specs. It's about the music." My translation is: The rumble on his machines is high, or he never tested them in the first place. Totally irresponsible if one is going to sell $10,000 TTs.

Your ears tell you how it sounds, the specs tell you what it DOES.

With the exception of a few (mostly japanese) turntables, the habit of not publishing any technical data became standard. I think the reason for this is mostly that the days of technical competition are over and the few tables that are still out there have found their niches.

If you want to get a (technically) great table, look for 2nd hand direct drives from the 80ies.

However, as these sweeties are getting in a tough age, a little experience in electronics for rejuvenation certainly helps.

Have fun, Hannes

The biggest variation I bet nobody measures is base vibration rejection. Some will skate if you don't tip-toe away on a wood floor. Some will couple the bass of the speaker into the platter and bounce the needle around at normal loud listening levels. Some allow you to dance on a wood floor right in front of it and never miss a note. I have type 3 now, a BIC. My highly rated first generation AR turntable was not nearly as good at rejecting floor vibration.

Lots of good input, thanks.

Werner, I did find some interesting info in the archives - like only 20dB channel separation! Seriously?!? I'm kind of amazed at some of it - like the FR variation, and nonlinear distortion performance in some places. If anyone wants to take a look, look at the 2008 archive, particularly articles on cartridges.

steten, your links dont work - could you post the titles of the threads, or fix the links?

Thanks everyone!

I'm trying to figure something out - Miller Audio Research, in their tests of cartridges (look in the 08/09 years) note that some tests are done 'vertical' and some 'lateral'. What is the implication of this? Is the track stereo (45/45), or mono? It sounds like the test track only modulates in the vertical or lateral directions? How does this influence things? Particularly, it seems to influence the frequency response of the cartridges...
