In Reply to: RE: The very "best" tube amps - or, the ones I'd most like to own... posted by A.Wayne on October 23, 2014 at 11:48:05
I wonder how many people get the wrong impression of an amp after hearing a sub-optimal matchup? Those of us who own amps with variable impedance switching or multiple impedance taps know what can happen in a sub-optimal matchup.

Its pretty easy to determine impedance tap to use once you know z-min.
My experience is that this doesn't seem to matter very much. One amp I had sounded best on the 8 ohm tap regardless of the speaker impedance. Another one seems to work better on the 4 ohm tap for one speaker even though that speaker doesn't drop below 6 ohms. That same amp works best at 8 ohms on a similar speaker and 8 ohms on my horns.
When I had Acoustats, despite dropping to 2 ohms in the bass and 2 ohms in the highs, the 8 ohm tap sounded always the best with that speaker regardless of the amp.
Go figure. Matchin is a great place to start but I would advocate simply trying an listening to determine the right tap.
