In Reply to: Sound Smith repair for ADC TRX-2 ? (Any Sound Smith experiences welcome.) posted by Wilson on May 14, 2007 at 16:10:44:
for the trx2. i had an XLM on the 707 for YEARS and they were all good ones. it also sounded great on the rabco st4 tt!a rebuild with the ruby/line contact sounds like an interesting twist.

Follow Ups:
All the ADCs (XLM, ZLM, & TRX) I've tried seem to have the low mass and high compliance the Grace likes.
1 - They are not low in mass,2- They are not in any way associated with the "LM"'s of ADC's past,
3- They require extensive break-in,
3- They seem to sound their best in a Medium Mass tonearm, not a low mass one like the Grace.

Thanks. Maybe, if I get the TRX rebuilt, I'll try it in my Rega arm. I was able to get good tracking at about 1.25 grams on the Grace, which made me think it was a good match for the arm. But when I went back to the ZLM, they really sang together. Proof is in the listening.Thanks again.

You may be right about the medium mass arm part. I know you are right about the rest. Anyway, I use the low mass Magnepan arm with good results, so I suggested an ADC arm as an alternative. I may be wrong about that, however, because the cartridge sounds great with the EPA-500's 14 gram effective mass armwand that I also use. I believe your comments warrant my edit of the previous post that I made.Thanks for pointing it out.
Is that they developed the wrap around the pivot point counterweight specifically to fake the cartridge to see high mass while the stylus navigates the groove wall while allowing vertical travel like a low mass arm.My Grado Ref Master picked up a great deal of inner detail on the Unitrac while it sounded just great on the SME arms.
The Unitrac is such a uniquely engineered tonearm you simply cannot just look at the effective mass and say this is what it might work with. You owe it to try everything on this tonearm and the TRX II works just fine on this arm.
I did not like my Denon DL 103R on the Unitrac. This was the only cartridge that underperformed. Interestingly the DL103R did not like my Technics SL1210 arm, either of my SME arms or my Rega arm. It really needs high mass. The Empire worked much better.
I love this darn Unitrac!
The TRX2 and TRX3 really smoothed out on the A501M wand on the EPA-500. I find it curious since this is MC-like behavior. Likely another hint of the cartridge's true origins...I have noit played with the TRX-1 at all, but it probably falls right in line with the others.
