Turntable Upgrade Suggestions


I currently own a VPI Scoutmaster turntable with the supplied JMW 9 arm and a Clearaudio Discovery Cartridge.
I also use a Thor Audio TA-2000 preamp with phono included and Thor Audio TPA 150 (150 watt monoblocks) amplifiers.
I use a pair of Quad 988's.I am trying to improve the quality of my vinyl by upgrading turntables. My first thought was to trade for the Super Scoutmaster, but then I was advised that that table could only hold the JMW 9 arm and was made to work with that arm. What if I wanted to upgrade to A Grahman Arm or A Rega Expressimo Arm. Would any of these work on the Superscoutmaster? I was told by adding an armboard which would allow changing of arms that this owuld degrade the sound, as the SuperScoutmaster was made to work with the JMW 9 inch arm. In short, for the $5000.00 asking price of the Super Scoutmaster can I achieve better sound with a different table and arm combination. Can anybody out there any make any recommendations based on what they have personally heard?

Scheu Premier II with dual arm (9", 12" plinth) and a 12" Scheu Classic tonearm inc record clamp and optional 80mm platter is costing me 2500 inc shipping from Germany.

Hard to beat; Teres that requires finishing is a bit more money for the least expensive one by the time you put a similar arm on it, pay the shipping, and tax. A Teres that requires no finishing is a hell of a lot more money; prettier, though, and probably a bit better than the Scheu. In this playing field they are all pretty damned good.
