Sirspeedy, I use my Townshends with Talon Hawks monitors (said to go to 40Khz flat) and they do indeed make a notable difference even here: set at 2 on their dial. I would suggest that you experiment with cables. I use the same cable as I use for my speakers and I think the synergy is increased. When I used the supplied copper cables there seemed to be a tonal imbalance with my silver core cabling. It seems more integrated now but I am still experimenting.
