Hello Jerry,
Although out of your league, I am running my EAD 7000 DAC (which I love BTW) directly into my amps, with a resistor based attenuator, I was also getting lean sound, but I solved it with very short speaker cables (10 inch) I am using mono amps, with the short cables everything fell into place right away....I would stay away from silver going direct.
I would also reccomend an Isolation transformer on the power line, It gets a fuller, cleaner sound out of your system.
I tried a bunch of preamps, I hated most of them and loved a couple, but distortion was always introduced to the signal path. IMHO
All the best
