Q Bias for Cary SLI-80

Cary co. says that proper bias for Cary SLI-80 is about 75mA.

But the allowed range of bias is from 75mA to 100mA.
Which one is the best from your experience?
I would share our information.

And, I heard that I can use EL34 or 6L6 outpu tubes instead of KT88/6550 and when using other output tubes, it should be same bias.

Is it right? If anybody knows it, please share it.

I tired EL34 on my SLI-80. EL34s are Antique Selections EL34 JJ Tesla Blue Tubes.

I adjusted bias as 90mA.

Sound is firmed up and more clear.
Very high sound is too musical, Bass is more tight!

It's big change! If you have SLI-80, try it.

How do you find the sound varies from 75 to 90 on the bias?
Thanks,

I figured I would bump this thread to see if anyone has played around with biasing on the Cary SLI-80 preferably in triode mode and KT88's. Preferences/Opinions?

I'll echo Artmaltman's question above.
