I upgraded from a Cambridge 640p to a Jolida JD9 (both purchased at Spearit-they're my local brick-and mortar). The Jolida is definitely a clear step up from the CA. It presents a bigger, fuller, more open sound. The music is much more "in the room". It came stock with a pair of Electro Harmoix 12ax7's which turned out to be better in my set up than Mullard re-issues.I bet this would be a step up,and the price is excellent for new.

Not sure if it's a step up or sideways, but I have heard/read that the Pro-Ject Tube Box II is very good value for the money. It uses dual mono circuitry for improved separation and has an outboard PSU. Runs both MC and MM (not together though), has reasonable RIAA specs. Has 60db gain on the MC side so should be good for low voltage MC's. I'm getting one in a a few weeks to hook into my Ming Da MC3R pre.Need a little help with a Phono Pre. I currently have an MC2200 amp, C-28 Pre and a Cambridge 640p Phono pre. Where is the next step up in phono pre`s from here? Needs to have at least 1 MC 2 would be better. Budget about $300 or so. :scratch2:
