As for the Exposure...it is the most fantastic sounding amp I have owned. I have had Luxman, Modwright...tube, Class A, SS, and vintage.  I have been north of $7K for an amp; and this is the one I kept. For the price-point it simply cannot be beat in terms of sonic performance. Admittedly, it is not much to look at but the music is all that matters. The Exposure is a powerful, fast, hard-driving amp with thump and boogie yet smooth enough for long listening sessions. I have found most of the British amps share this sonic trait. Enjoy the pursuit!
