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!

Dear @singingg : You bad experiences with the AS TT PS can happens with any TT no matters its price level and that kind of experience really can’t speaks for the AS high quality levels.

 

My 2 AS TT that are running today I bought second hand from an Agoner friend that by coincidence just posted in this thread @aoliviero and he better than me knows for sure how many years has my TTs.

 

I have each one running with one motor and running with ONE motor PS only that I modified with switchs for I can choose between 3 motors and that PS never showed any single trouble it’s spot on. Yes the 3 motors can run at the same time too, if need it.

Dear @mijostyn @plinko  : I agree that we can't overdap the TT and even if we could that's a good notice.

 

In the otherside AS TTdoes not needs multiple motors, more than one is only an alternative for the owners. It's really need it more than one? certainly not. I used mines with one motor with out any single issue and this I do for several years. Even that I made tests time to time with a second motor playing and in no time my way of thinking about changed.

 

About motor torque per sé means nothing because all is relative to the overall TT design. The AS is low torque because has a heavy platter that under playing only needs little help to spin due to its very good inertia. Overall design defines TT characteristics.

When using my units I give it a little help with my hand just to start and spinn at 33rpm in no more than 10seconds. Not big deal..

Dear @plinko  : I know you are not a " new comer " and 7 years you asked for a plinth for the SP10MK2 and you named here too. 

 

Any TT in that price range are a good TT and that's why audiophiles buy it and due to those sales those manufacturers exist. As any other analog audio item all different TTs have its own trade-offs and you are an audiophile with your unique MUSIC/audio priorities and the TT is only a link in the analog rig and everything the same could be that the more important items are the cartridge/tonearm combinations.

Today there are not bad TTs and many really " surprising " ones like the RP10 with its bargain price.

In AS no one cares about AC vs DC because by design the external control motor develops its own electrical " wave ", it's immune to electrical fluctuations. Between others I own AS.

Btw, no one has any true benefit listening a TT in a way different room/system.

 

Regards and enjoy the MUSIC NOT DISTORTIONS,
