I very much doubt it as the 6 series was never designed to run with a PSXR. If you want to stick with the 6XP you would perhaps be better adding one of the Cyrus Power Amps and bi-amping (if your speakers have a bi-wire option). Cyrus do have an upgrade option for your 6XP to the current 'Classic' amp but this costs around £1500.
Thanks, for the reply.
I had a feeling that would be the answer, the upgrade wouldn't be worth it and, perhaps I'll try the power amp route first although, would a power amplifier only expand upon the sound of the 6xp or, would it actually enhance it?
I like the sound of it but, I find it can get a bit "shouty". Now whether that's down to my speakers I'm not sure, the Quad 12Ls are a little shouty but only when the volume is reasonably high, the other speakers are Cambridge audio SX60s, very good speakers but again, can become a bit shouty, interconmects are NVA, speaker cables NVA, cd is a Cambridge audio CXC transport with a Cambridge Dac Magic 100. Got a feeling the dac could be improved? Going to try some Chord speaker cable but, highly unlikely that would make much difference.
Thanks again for the advice.
