VPI TNT Turntables

sbank-

Understood.  My initial comments had nothing to do with speed controllers, I was curious about why a putatively undersized flywheel seems to make such a difference in SQ.  Somehow, the thread got pulled in the direction of arguing over the physics of speed control.  I don't mind sharing my knowledge of that subject, except with people who refuse to learn anything from the exchange (it's difficult to make people understand something when they already know so much).

1 - the other guys are correct - you'll end up buying a used table with some kind of arm on it

2 - the TNT works well with either a linear tracking arm or a pivoted arm  ( use the SME V but have listened to the ET)

Phoenix just to clear the air Im not against you or your product either. I have not heard it yet.  I think it looks like a well-made fairly priced product.  But I am leery given the premise of the whole thing. To me it's theoretically better to hold a constant speed, or attempt to, then to have an ever-changing, corrected speed. I realize neither one is perfect though so they both may work equally well in practice.  I think all the concern over belt creep is way overblownjust to sell us poor saps something else. But that is audio in a nutshell. And as S Bank said you really should identify yourself as has been brought to your attention before. 
Regarding the TNT ET Combo the op is after I think he is on the right track. My table came with the 12 inch arm and I sold it and bought an ET and pocketed some money. The ET far outpreforms the 12 inch arms as well as 95% of the other arms on the planet. The ET is stupid performance for the money. Where are you lady you should be somewhat mechanically inclined and willing to fiddle. That does not mean it goes out of adjustment as some people think I just mean in the learning phase you have to play around with it. 

ET designer Bruce Thigpen is one of Hi-Fi's true geniuses, and all his products serious over-achievers, very underpriced for their performance capabilities. Why isn't ET higher on the radar?! VPI's are THE table for the ET arm.

I think the ETs aren't more popular because people are afraid of them.  Although they shouldn't be, while very different the set up is actually much easier than with a pivoted arm once you figure it out.
