I have a couple questions regarding a few models of preamps. Ive been looking at the dc1 -dc2 and mc1 models. has anyone heard any of these? if so which would you recomend? I want to upgrade from my adcom gtp500. I have a couple amps with balanced inputs and would like to start switching over to something with those inputs. I also like the upgradeability of the lexicon products. But......... I am concerened about whether any of these 3 are upgradeable to the new hdmi 1.3 inputs for hd dvd or bluray. I dont watch a lot of movies per se but i do buy a lot of music videos and am looking forward to the new audio formats that will come with those formats, and would like to be able to enjoy those with a minimal cost. If i could send any of these off to get upgraded with the software and inputs it would be great. Also any other thoughts or ideas will be appreciated . THANKS IN ADVANCE AND HAVE A SAFE AND HAPPY 4TH OF JULY ALL OF YOU.
