a few comments:
- Whenever biasing an amp, it has to be on for at least 2-3 days to make sure that the ps is completely charged
- auto bias would be nice...if prices could be held in check, and if it wouldn't interfere with sq
- yes, it is impossible to stick at 0.00 mV pretty much with any amp...the fluctuations you see are mostly due to fluctuations in your AC
- with the offset, anything under 5-10 mV is acceptable...not as good as close to 0, but you wouldn't be able to hear the difference.
- yes, it is true that the AC average in the US used to be 119.6 V 10 years ago, via one Energy study. However, as nearly 100 % of my customers across the country measure their AC so that I can nail down the bias for them individually, I pretty much see 121.5 - 122 V as the median these days...of course not the same for winter or summer...
- yes, it used to be 10 K, but we have changed to 22K years ago.............
- man oh man, it takes a lot to make any of our amps sound thin, especially when somebody rebiases them...and especially on the Extremes...just shows you that some associated equipment will indeed stamp its own signature on the sound,,,again, synergy, synergy...there is no silver bullet.
Lastly, as for the German solid state sound....ok, the first couple of years in the late 90's and early 2000's we pretty much duplicated the design, but over the years I personally tweaked and optimized the shit out of them, making them extremely realistic and a bit on the full, rich, and warm side.....took me years to be where I am now. But it is nice to know that our amps are decent for the money though.....
