Cary SLP 88 - will be perfect or The New Sonic euphoria, the Rotel is a nice amp and with Cary it'll be an excellent choice to keep after several upgrades, So Its been one piece I'v worked around. Its been modified at the stage of new oil caps, Which was a monsterous upgrade. That pre contend with many pre to the 10k point. The sonic Euphoria is also in the price range And as well is killing the likes of many ultra-hi-end pre's.
I own a Cary & have ordered the PLC fully balanced. Its rare for me to keep a preamp after a new purchase. Thats how good the slp88 is. My power source is a Plinius SA102, and prior to that it was a Aragon 8002-Very close to Rotel, the Aragon may be a bit warmer an less analytical compared to the Rotel.
