As it turns out, I'll be picking the amp up tomorrow. I'll be running it in a bit of an unusual setup, so results should be interesting. My main amp in a Wyred4Sound STI-500 integrated. I'll be comparing the stock integrated to the Modwright being driven by the preamp outs on the integrated. I'll post impressions once I've formed 'em.
FYI, rest of the system is a Naim CD5X/Flatcap2X front-end, Harbeth Compact 7ES3 speakers and most cabling from Audio Art's SE line.
