What tube amps for the Quad ELS 63
I have recently purchased a pair of Quad ELS63's and am looking for some advice on a tubed amplification for CD use only. I have been using them with a Linn Classik integrated CD and amplifier and while they are OK they are hardly musical and involving. All thoughts appreciated!
