Well Tempered Classic or Technics SP10Mk2

Bob, looks like you have sufficient response to make your decision. But I'll add a little reinforcement.

Years ago I owned an original (square motor) WTTT and arm. It played music but was responsive to improvements such as the new black platter, a clamp on the fluid cup, and damping on the arm tower. Still, as Lew suggests, the WT arm was always in question. For one example I could never get the same tracking force measurement two attempts in a row. What kind of precision does that suggest?

I replaced mine with a Kuzma Stabi/Stogi Reference table and arm. This was a significant upgrade offering extended bass, increased overall dynamics, and much better decay, most noticeable on piano. More recently I've listened to an SP-10 Mk2 and even with a (temporary) compromised plinth, it shows potential for bettering the Kuzma.

The step from a WTTT to a Technics should be a no-brainer.

OK, I have heard the SP10 II with the EPA-100 arm and it was a nice "vintage" turntable, but when I heard it with the Triplanar (can't remember the model) it was a reference playback system.

I know someone with the SP 10 and EPA arm, so I am going to go give it a listen again since so many of you find it to be so good. Maybe I was missing something.

I have been thinking about an SP10 but with a modern arm, but maybe I should just use the EPA-100 if it's that good. Does it need to be re-wired?

Ahh, I should just ask Albert Porter, he knows everything about these tables.

Dear MDT, I own a Triplanar and love it. However, with reference to the EPA100, my comments were based on hearsay. So many disparate reputable persons say it is excellent (e.g., Mosin, Raul, etc) that I have come to believe it IS excellent. I have no idea which arm would win a head to head comparison. The point is that you cannot go wrong buying an EPA100 at a fair market price; at worst you can sell it and apply the cash to a Triplanar.

MDT,
As important, or more, than the tonearm is a heavy and well isolated plinth for the sp-10 tables. I currently have two identical double arm plinths. For two of the four tonearms, I use the EPA 500 system(seven different armwands in all). The other two arms are modern high end arms. The EPA arms compare surprisingly well to even the Air Tight PC-1 Supreme on the SME 312s Magnesium. For fun, I tried the Ortofon MC10 which I bought for $150 on the a501L wand with surprisingly good results.
Rewiring the EPA arms may help but I've done nothing to mine yet and they perform very well. Lewm is right, for a relatively low price, you can try the sp-10 and EPA arm with little loss on resale. I doubt resale will be a consideration however.

The EPA-100 was and still is a very good tonearm. Its' current selling price makes it a bargain compared to VPI, Nottingham, and Rega crap for the same and even more money.

But to say it's a contendor for the "best arm ever made" is really foolish.
