I want to upgrade my TT for about $2K.

I'm a very happy Teres owner, but you might also consider a Nottingham Spacedeck in that range, assuming a Rega can be easily fitted to it. Someone here or on VA will know.

If you can find $2250 the Teres 160 is a big step up from the 150.

You should also give serious consideration to the VPI Scoutmaster, which has a retail price of $2400. The Scoutmaster's tonearm (the JMW 9), which is included in the price, is far superior to the Rega RB300. While I certainly have a high regard for the Nottingham Spacedeck, I still think the Scoutmaster represents a better value.

What about the VPI Aries?

I mean in comparison to the Scoutmaster.

I think Doug's recommendation for a Spacedeck is right on. Go the the Audiophile Systems website and click on "Where To Buy", then click on "Nearly Perfect Sale", and scroll down to the Nottingham section. You will find that you can buy a Spacedeck/Ace-Space combo for $2399.20. The new Ace-Space is a nice step above the orignal Space arm, which was already worlds better than a Rega RB300. My advice is to snatch up that rig and sell your Rega. You won't be disappointed.
