Hi all, I recently purchased 3910 & 3805, but am not completely happy with stereo cd. I've been advised to try a stereo amp update first. So, the question is, can I run my 3805 and a stereo amp into my Quad 11L's, since they have 2 sets of terminals for bi wiring/amping, & so I wouldn't remove the jumper plates? Naturally, I would make sure I didn't have both amps on at the same time........doh Also, recommendations for stereo amp for not more than £250. Cambridge Azur 640a or second hand? Many thanks, Tim.
