unbeatable Class A integrated

The Luxman 590 bench tested to 90 w into 8 ohm in one of the reviews

Can you post a link to this review please?

Not in Class-A, Class-B maybe if the rail volts are higher than for 30w which is unlikely as the heat factor goes up exponentially with higher rail voltage.
Doubtful looking at all the other specs from others because then it would be classed as a Class-A/B amp, those piddly small heatsinks couldn’t take it, they look lucky to even take 30W of Class-A.

The a New Krell 300 is very good with a sliding A bias circuit 
very good detail and a nice slightly warmer balance with many options like hdmi inputs and outputs to hook to a hired tv 
dac board is optional.for around $8k retail and made in Ct USA .

The Krell has a patented sliding A circuit that applies in pure class A as current demands up to around 90+ wpc  then goes into  Class A  to 200wpc 8 ohms ,400wpc 4 ohms. A very  good sounding unit ,andthe preamp section is  a dedicated class A section .

Do you mean in reference to this week's favorites or last week's favorites?
