Every cdp can be used direct to your amps with the passive Placette RVC (remote volume control). the Placette is less colored (more neutral) than any attenuator found inside a cdp (a generalization that i know no exception to although one may exist). the only issue is that since it is passive the interconnect from the RVC to your amp(s) should be short, your cdp needs to have reasonable output and the input impedence of your amps needs to be sufficient (high enough).
the Placette RVC is $1000 list price ($1800 list for balanced). it is very small (about 6" x 8" x 2") and will go about anywhere. it has bettered every active preamp (some over $14k) in my system.
