om...
Today I have an old Rotel 820BX3 that sounds good for an hour after
which I get tired of it (and consequently doesn't listen very
much...). After reading on the net I got the impression that both the
Sugden and 300B amps are less "tireing" to listen to. I have small two
way speakers (Quad 77-10L - 84db) and I understand that the 300B likes
more easy driven speakers than this. But I normally listens on low
volume (9 o'clock) so I am hoping that the 300B will be usable for me
anyway.
I don't have the possibility to listen to any of the amps so I am
hoping to get some comments from someone who has.

An interesting and very inexpensive choice could be the Gainclone, because
the component count is so small you can alter some of them easily and you do
get a different sound.

I made mine with Polyester input caps and later changed them to
Electrolytics, the result was a slightly slower and more rounded sound. I
was frankly, astonished, I'd read that this happens but until I tried I
scoffed at the idea. I prefer the Electro caps. I've never changed the
resistors though, I used 10% carbon film bog standard ones, but I'm told
that changing these to 2% metal film ones changes the sound again, and that
these give a more 'solid state' sound, whereas the carbon ones are more
'valve' like.

Heres a couple of links to start you off,
