Usher TD-20

I’ve looked at the amp several times. Sounds overall like it’s a good amp but the thing I keep reading is the high end is a little rough.

@mofojo That’s a little counter intuitive given the amp’s Class-A architecture.  I also have to believe the makers of the speakers chose an amp to work optimally with their own speakers, but there are always the all-important personal taste and system synergy factors that come into play, so who knows?

Yeah dunno there were just several reviews and the only bad thing they had to say was about the highs. Not they were bad but just not as refined as the rest of the range. I came close several times to pulling the trigger on used local ones. 

You can also up the bias on the Usher amp to make it sound better.

Thank you so much for your responses. I agree that the TD-20 is a warm and lush speaker. Rowland is very much in the same vein. So the system is too warm and lush, and I don't have enough space in this room to bring them well out into the room. I will be adding Stillpoint Ultra 7's (just waiting on the proper thread size) and may consider adding lead shot to the lower chamber that is behind the faceplate on the front of the speaker. These tweaks should at least tighten the bass a little and reduce the warmth a little bit. But where you all have helped the most is with regard to the Gryphon electronics. I had no idea that their tonal balance was warm as with Rowland. I definitely don't need more of that. Never thought I would be shopping or a bright amp. But if Usher's amp is a modified Threshold that gives me a good idea of what I should be looking for since I know Threshold well. Thanks again!  Ted
