I have the Special 40 and two amps.
Hegel H95 - 60W
Pass Labs int-25 - 25W
Sound is so much better with Pass Labs, even if it is half less powerful on paper. Pass Labs int-25 is such a robust and marvelous amp...
Hegel H95, doesn't run in the same league, and the 30 more Watt do not help in any way. Sound is dull and flat compared to the other Class A amp. Anyway, working & driving well the special 40.
Hope this helps ! (even if an old thread....)
