Cheap class A intergrated power.....

I do'nt know if they come up in the US, but do'nt forget the good old Sugden A21 integrated. It's quite cheap, very reliable and wonderfully musically envolving in the right system. That means reasonably sensitive speakers, but presumably you would'nt be considering class A if you did'nt have those. I agree with JKaway, I have never liked Musical Fidelity much and I'm British, Sugden is a wondeful, but less well known company, with to me a much more envolving "house sound"

If you're talking separate pre/power, then the Monarchy or of course Pass labs Aleph series are a great choice. I use an Aleph 3 and it will have to be peeled from my grasp on my deathbed. Both are to be found at good prices in the used adverts
