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
