Mark Levinson Integrated....hmmmm... 585 look no further
Also nice if a used one is wanted, but was double the new price, (if adjusted for 5 years time), and it also only got 20w out of it more when tested before it shut down into 2ohm, so for the money this new one is pretty good.
The new one also stays flatter into the simulated load test, even though it has higher output impedance "less feedback?" but more current?
So the new has better low load impedance control but doesn’t have as good distortion figures, because maybe of using less feedback.
This is the real interesting part it runs 2 of it 8 per channel transistors in pure class-A, it has an automatic adjustable to max Class-A bias according to heatsink temperature.
