Ditto here, Tommy has been nothing but totally stellar with two problems I had, (Both my fault I should add) and took care of both. I snapped a binding post off with pliers using my left hand ..... long story short after rotary cuff surgery wanting to change speaker cables, the other was a loose falling speaker wire that sparked out taking the entire Right channel out. Tommys response was at the time ... glad it didn't take your Right speaker out ..... nothing but utmost total class from the man!!
Not sure what Mr. Os problems are regarding his way newer Cherry amp ... was Tommy supposed to install a new protection button or what, and I am sure the insides have been upgraded as well from his 4800A to Cherry version. Maybe when Mr. O calms down a bit his rant will resemble some sense, because as of now he is the first whiner I have read on this entire DAC site!!
