Class A amplifiers - which are considered the best

Same topology Unsound, just different models in the same rang as the KSA250 range, all with partial Class A not even 30% of their full output into 8ohms.
Like I said the only ones to have high % of Class A compared to rms output, was the fan forced Krells of 80's.
And after that the only model to get near them with good amount class A % was the Plateau Biasing (Anticipator Circuit) Krells "S" models with their Xmas tree bias lights, but they never sounded as good from many a report.

Cheers George

I thought the Plinius SA-Reference which claims 2x100W Class A was already quite a big claim, but has anyone seen a Karan S400 which claims to deliver 470W x 2 Class A in an even smaller chassis!

Vitus audio ss101.

The mighty Karans are most certainly up there with the very best if you're into natural sounding SS.

Goergelofif, the Krell KSA 80 and KSA 200 (and their mono counterparts the KMA 160's and KMA 400's) preceded the KSA 250 by a couple of years and were of different design generations.
