I think either turntable you noted will play records beautifully. It's a very subjective choice. One note, Clearaudio has a Performance DC with Verify arm in the $3000 range now. That in terms of dollars will be a match to the RP8.
If you want to save some cash, the Concept will probably be a nice choice. It's going to compete with the Rega RP-6. Also to add the Pro-Ject PerspeX Turntable and add the Pro-Ject Speed Box.
But if I had $3000 or so to spend on a new turntable I'd look at RP-8, The Performance DC, VPI Classic 1 and to add the Pro-Ject Xtension 10 Turntable.
It comes down to dollars & cents, what and hw much do you feel comfortable in spending.
