Default Experiences of Class A solid-state ?

Eeyore said:


Have you ever spent any time listening to a true Class A solid state
amplifiers ?


Any comments on how it sounded compared to any other types ?



I have extensive listening (and building) experience with hybrid amps,
a tube driving (one or more) complementary pairs of MOSFETs biased in
A.

Because they're my own designs, I don't know how to compare them to
commercial amps, since it's been a long time since I listened
extensively to a commercial amplifier at home.

From recent demos I did with them, the most comments I heard were
"effortless sound, somewhat restricted, but detailed and powerful when
necessary".
Also, the terms "forgiving" and "smooth" were uttered.
Some people preferred them above a pair of modified Hypex UcD400AD,
though. And of course, others did not.

I guess that means they do color the sound a bit.
In fact I know they do, I *intended* them to sound like that ;-)

I still think my KT88 monsters that came ready recently, beat them
wrt. placing and detail, but they're rather sensitive to the kind of
speaker attached, and do deliver less power because they're wired in
triode.
The hybrids are more "forgiving", they easily drive 2 Maggies in
parallel per channel.
