Rega RP3 or Pro-ject Expression III?

Both kill CD. I've had both brands...both are good.

I really like my Pro-ject II Xperience Classic, but if you're set on those two, I might suggest the RP3. I haven't actually heard the Elys or the Sumiko Pearl carts, so I'm not any help there. I heard both of those tables with Grado carts, and I'm still using the Sumiko Blue Point No 2 on my Pro-ject. I think both are good decks.

Go Rega... I know I'll take heat, but Projects do not play the music. Period.
Compare, and write back...

I own a 1Xpression. Would have bought a Rega P3 if I had a local dealer at the time, to be honest. The P3-24 was even better than the P3.

Haven't heard nor seen the RP3, so I can't say for certain about that one.

The Xpressions are very well made and reliable IMO. Not a single problem with mine in about 7 years. Rega's decks have also been pretty solid.

If you buy the Xpression, replace the stock Oyster cart as soon as possible. It's absolute crap. I have a Dynavector 10x5 on mine, which is the upper limit of carts on it IMO. The Xpression's strong point is the tonearm.

I'm not a fan of Rega's carts at all. A lot of people like them though.

I'm not trying to get you to spend more money before you buy, but you should take a serious look at either Pro-Ject's Speed Box or Rega's TTPSU once you get up and running for a bit. Both a a very good upgrade to their respective deck. They'll easily take it up to the next level (again, haven't heard the RP3; basing this on all previous P3s).
