Following a quick bidding bout on e-Bay, I have just managed to become the proud owner of a Meridian 557. :MILD: At the moment, I'll have to use my Audiolab 8000a as a pre-amp but I intend to get a Meridian pre. Now, I know that the 501 and 502 are pretty cheap as pre-amps but they seem to be as bit thin on the ground. Can anyone advise if any of the A/V controllers are good pre-amps (eg, I believe the 541 can act as a stereo pre)? Also, what would be a good interconnect between the pre and a power? Would a 502 + XLR be better than a 502 + RCA? Thanks in advance
