Gary, (Muffley) great to see a familiar (audiomart) member on here. Used to talk to you all the time (about D-150 amps) years back. Coming from you, the quicksilver is well worth a listen. How much of a pain is the 2 volume control setup to get used to? The price is set as Quicksilver always did. An honest product. My SP-10 has long been retired due to an inadequate line section. Thanks for the tip. Forgot all about this company ever since the bestselling amps in the late 80s.......Frank
