coupling or decoupling of vinyl to/ from platter
If a center weight is used that is very heavy, let’s say 2 lb. the lighter records will lift from the mat. This happens because the mat depression edge will act as fulcrum. This information tells us we should use a center weight tuned for the... 
coupling or decoupling of vinyl to/ from platter
In my case, with a Classic 1, VPI recommends against a mat. To reiterate the original question, what's the theory?I explained the job of the mat- it is ideally a damping device. The problem is that when the stylus tracks a groove, the vinyl reson...

My forecast is the ZEROs aren't going to offer much in this installation.

Yes, but can the M-60 power these to rock music levels?I play in a rock band. Audiophiles in general don't play **any** system to rock levels :)

^^ Yes! We have a number of customers that run ETs as well, and very successfully.  
coupling or decoupling of vinyl to/ from platter
If the LP has to be decoupled from the platter to get rid of motor noise, the turntable has a really serious problem and should be repaired. I think we can discount that explanation.A proper platter pad does several things at once, that is if its ...

Doesn't using zero transformers defeat the whole point of an OTL amp? It's putting  a transformer in and makes it similar to a non OTL push pull tube amp.'Defeat' as used in the question above suggests that an OTL is trying to do something that ... 
Balanced and RCA concurrently?
If you are trying to drive the amp with two different sources, assuming that one of them is not playing, the presence of the other will load the source that is playing.By 'load', imagine carrying ten pounds for ten miles. Not so bad if you are in ... 
Tri-Planar Vll "SE Upgrade"
Any arm can do 70 microns or even 80. Its no big deal and Triplanars can do it too no worries.I don't need a test LP; I can perform tests using my lathe.The technical story is easy to understand. I'm sure most that have read this far followed it w... 
Balanced and RCA concurrently?
There is no danger, but it won't work. The other sources plugged into the amp will load the preamp, and vice versa.What you need is a preamp with more inputs, and possibly also a balanced output. 
Tri-Planar Vll "SE Upgrade"
Folks, just so you know, 50 microns is about the same as 2 mils (which is how groove deflection is measured in the US if you have American-made LP mastering gear). Many systems use microns these days as many cutter systems are European-made. 2 mil... 
12AT nos , flash at start ?
When you see that flash, its the flash of quality. 
difference between an active and a passive preamp?
@celo , maybe.The real number to look at is the output impedance of the DAC at 20hz. If that is the same number then I would say your chanced are good with a passive control, if you keep the cables short.

@nandric , the above and this:Interestingfinding for someone who does not own a single test record andalso does not believe in test records. Shows that you are an adept at the Stawman. I never said I don't believe in test records, I just said I do... 
When and how did you, if at all, realize vinyl is better?
But both are not detailed specific related aspects, they are generalizations... and are laid on top of the scenario as if they are the perfected fundamentals of the question or equation.Since the question obviously remains unanswered in a way c...
