I scored an Aragon 28K MkII today that looks very nice and is well thought of in web nets. For $300 I found it hard to pass up (even has a remote). It is one of those high-endish preamps that scoffs at the idea of tone controls (which I personally find useful, even if they allegedly add noise - so shoot me). Will post a report later. I have to post a report on the Black Beauty Bob amps w the KT-88 tubes, on this Aragon pre, the Rega RP1 w performance pack, and the Reference MM 3as. And the Jolida JRC1501 hybrid. And the Sennheiser HD 265s. Just writing this paragraph made me tired! Stay tuned.
Get the USP-1 and report back! All I hear is good, and for the price you cannot go wrong!
