Mike, are you in for a round of PC-ABXing our amps? :-)


Might could.


Give me some time to get my PC's soundcard up to standards and to
practice some with PC-ABX and I'll get back to you.

My proposal is as follows: we both make wav. files available of our
respective amps, post them somewhere (or send them to Arny?) for all
to compare.

The output voltage of the amp shouldn't exceed 20 V RMS in 8 ohms,
which is loud enough, at least for me.
The power bandwidth at this output voltage is 5 Hz...100 kHz within 1
dB, which is beyond the scope of any sound card I know of at this
moment.
THD is below 0.5 % at 10 Hz, 1 kHz and 10 kHz up to 20 V rms output
voltage, with the 3rd as the dominant harmonic.
Output impedance 1 ohm over the entire frequency range mentioned
above.

Not really outstanding figures, but I suspect it'll do :-)

We have to agree on the source material and composition of the dummy
load, as well as the desired output voltage.
I'm assuming your sound card is good enough as to not be of
consequence.

You can reach me at s.a.w.i.(at)myprovider, remove the dots before the
(at)-sign. My provider should be obvious, it's in the header.
