A/B testing set up......

Posted by vinnie2 (A) on October 23, 2014 at 05:42:04

As predicted previously by others, I find I can not change between two amps quick enough for proper A/B testing even though I have a switch that lets me select one or the other amp to go to the same set of speakers. It still takes about 20 seconds and I have to get up from my listening position to do it and turn off one amp and turn on the other.
I would instead like to be able to leave both amps on, balance out the volume levels, and then switch amps from my listening position.
I have enough selector switches to do it, but my problem is keeping a load on the amp that is not switched in to the speakers.
I did a little searching on the net and found one suggestion to put a 150 ohm/5w resistor across the terminals of each amp so that they have a load when not switched in.
Does anyone have any experience with setting this up? Does the above method work or do you know of a better method?
Thanks
