Jadis Orchestra Ref + Pre-Amp?


Wondering if it is possible to use the JOR as a power amp, with a Pre-Amp and CD feeding in, and whether this would help with the avoidance of clipping - I have no background in electronics, so I'm unsure whether the pre-amplifier boosts the signal in a meaningful way, and if so whether this translates to an easier time for the JOR - the issue at the moment is with solo piano music, where there are large changes in dynamics and a crash of chords brings distortion, which sounds like clipping, albeit 'soft' clipping; needless to add turning down the volume prevents this problem, but then I'm listening at a lower volume level than I've been accustomed. I was warned about the amp being a bit underpowered for the difficult load my speakers represent (Wilson Cubs) - distortion never occurred with a previous, more powerful, ARC amp (D125). I still have an ARC SP9MkIII pre-amp.

If the above is possible, would it be preferable to run the JOR with the gain wide open, and use the pre-amp to attenuate volume, or the other way around?

Thanks for your anticipated help.
Rob.

I have a JOR and have driven everything from Quad ESL 63's, Spendor SP100's, Rogers LS 3/5a (15 ohm) and various Sololiquy floor standers with it, and to some pretty good volume levels, with no trouble at all. Actually amazingly strong tight base and overall delicate articulate sound. I use the KT 90 tubes normally in it.
