I'm thinking of upgrading my Musical Fidelity XLP Phono Stage and am leaning towards the EAR834P with Volume Control so I can connect this directly to my 8000P power amps, has anyone has any experience good or bad with this unit? There's also a Project Tube Box on ebay which finishes tomorrow and a new MEIXING MINGDA Valves MC/MM phono stage, anyone had any experience with these products? Cheers! Spenny
