Hi, I've got a Linn Aktiv Crossover box for my Linn Keilidh floorstanders in order to active bi-amp them. I need 4-channels of amplification (of equal gain), 2 for the bass, 2 for the tweeters. Very high quality music playback is my requirement, budget £500-£900. The passive crossovers in my Keilidhs will be disconnected, leaving each amp channel a direct connection to each speaker driver. I currently run the Keilidhs off a Denon A10SE, but I won't be able to use that with the Linn Active configuration. The secondhand prices for Linn power amps seem very high at the moment, so I'm looking for alternative recommendations. The 2 channels for bass don't have to be identical to the treble ones, but have to be identical gain, so I'm probably looking at a pair of good 2-channel amps ot a 4-channel+ power-amp. A 5-channel Parasound is available new at only a few hundred quid more than a pair of older s/h Linn amps, I'd also get a freebie 5th channel to run my Kef 200C Reference center, which would mean I can sell my Denon POA-T10 2-ch power amp. I understand Active operation relieves some of the strain off the amps and gives an efficiency boost, as well as using . I'm looking for quality, not necessarily more power than I'd need. Anyone compared a Parasound amp for critical 2-ch Music playback? Your experience and comments appreciated. regards, Rob.
