As my current amplifier is in for repairs I'm considering trying out some SS options for my Quad 63's.

Usual suspects like the Quad 606/909 etc seem the way to go. However I have heard some left-field suggestions like the Nakamichi 420 and Musical Fidelity P170 can sound even better . . . I like the Musical Fidelity's "dual mono" power supply and how the first 20w are class A then class A/B after that.

However I suspect that a current dumping Quad is suggested by most for a reason, however I'm slightly put off by reported reliability issues towards the end of their production.

Certainly a few nasty rumors about the newer Quad QSP's suffering from cheap parts and having constant trips back to Quad (IAG) to deal with design failings.

Any suggestions most welcome

Cheers,

Chris
