The *ideal* amplifier has no sound of its own, and no amplifier is ideal.
However, for many years now, amplifiers come awfully close to the ideal, and
consequently, except for the nittiest of nit-pickers, I subscribe to the
view that no (half-decent) amplifier has a sound of its own, and
consequently all sound the same.
Certain conditions apply, like operation below clipping into loads for which
the amplifier was designed, using music signals.

I've noticed that the Audiolab's I've got are rather boring in that
respect;!.
As are the ESL's..no fun at all.. Perhaps I ought nip over to Keith and
see if he's any spare horns I could prise off him at a decent price
