If you are after quality, THP make good amplifiers. You can now buy them in
the USA. (Also for VK Tokyo is nice and close.relatively)
The market for Elecraft to produce amplifiers that are significantly better
while not costing very much more than the THP ones is fairly limited.

Did you try a complete reset? This could be a DSP issue. It could also be a
