I tried upgrading power cords and speaker wire. Sound is now somewhat warmer and fuller but still emotionally uninvolving. Dr. Lou, I haven't heard anyone describe the 1072 as you have. It was the first piece of upgraded gear I added to my old Nakamichi RE-1 and B&W P5 setup, and it was definitely a very musical addition to my ears-- certainly not hard or coarse. So, I tend to believe, that for my ears, at least, that's not where the problem likely resides. I'm going to try some different, more powerful amps. When I listen to the Rotel amp and cd player through Grados, the sound is still on the chilly side for me, which would seem to suggest the amp is contributing the coolness. Thanks for all the suggestions!
