Abe> The only way I know how to describe it is that it is totally transpsrent. The only thing I have a-b'd it against is an Adcom GTP450 which I use in a bedroom system. There was no comparrison. It wasn't like removing a sheet, but more like removing a thick blanket from the speakers. I have considered upgrading my amp (CJ MF2200) and cdp (Theta Miles)but have never really considered changing the preamp (CJ PFR) If you are considering a PFR I don't think you'll regret buying one.
