Acoustic Signature turntables


I do not see a lot written about these turntables by end users. Can anyone share experiences or opinions on reliability, use, and design considerations?

Some of my observations or questions (keep in mind these are naive as I have never heard these models and I may be wrong about assumptions made).

1. Why the multiple motors? This is the one I struggle in understanding. Is the AVC (motor vibration reduction) that they provide somehow enhanced when working across more than one motor? How is this different than other motor vibration reduction methods such as the Rega method? Whether additional noise or reduced drive capability, who knows (?). How long to get up to speed?

2. Standard bearing vs inverted vs magnetic. I suppose there will never be consensus but noticed AS steadfastly implements standard bearings that focus on the materials used.

3. Platter dampening. Their method seems to work well. However, I noticed comments about earlier models being overly damped. The dampening increases up the product line.

4. Very heavy platters compared to some competition. Even the lower models have very heavy platters so they seem to think this is important.

5. Subplatter vs no subplatter. AS seems to have moved to subplatter design for models that can take multiple arms. Did they always think this method was superior?

6. Tonearms. Not much out there about the tonearms. Seems once again standard design but focus on materials…carbon fiber and bearings.

7. Back to motors. AS uses AC motors. Kuzma insists on DC. I guess I can try to read up on the differences and why manufacturers prefer different types. Any thoughts here? I am probably not be smart enough to understand the finer points about turntable motors (lol).

8.  Warranty.  AS seems to offer the longest warranty.  As with other warranties, what good is it if no design specs and performance tolerances are published?  Seems few turntable manufacturers publish relevant specs these days.  On one hand, I understand why in dealing with picky audiophiles and on the other hand, unfortunate.

Would appreciate additional thoughts. Thanks!

Plinko, You are making this much harder than it has to be, and it’s hard enough to begin with, to choose a new turntable from the myriad of choices that are available. What you care about is how each of the parts functions as a whole. In each case you are buying the sum total of the designer’s choices. So I would forget about your 8 questions and just listen and choose a turntable, not a motor or bearing or etc.

But, as regards multiple motors on a belt-drive, there is a rationale for two motors set 180 degrees apart, so as to even out the side stress on the bearing well and spindle. Three motors is already overkill, in my own opinion, and the noise of one or two motors ought to be lower than the sum total of noise from 3 motors. Just my opinion as an inveterate DD aficionado. (Yes, by the SP10R, your best idea.)
