"in business again ..."!! You people kill me - most two-channel hi-fi "companies" are neither "in" nor "out" of business at any given time in the traditional sense of the term, as probably 90% of them are a guy working out of his basement or garage when he gets home from his day job. Most of the others are two to four-person operations that don't keep what most people consider regular business hours. You can count on two hands (probably one hand these days) the ones that have $1 million in annual sales - there are very few B&W's and McIntosh's. This is not to say that they are fly-by-night or unreliable - most in my experience are responsive to their customer's needs - but "Supratek" is really a just a talented gentleman named Mick Maloney and shouldn't be talked about like it's IBM.
In two-channel audio, the first question is whether the man behind the curtain will honor the warranty that came with whatever he sold you and/or whether he is still alive to perform the work. The next question is whether whatever he sold you can be fixed by somebody else in the event the answer to either of these questions is "No" (if it's tube gear, usually yes). For this reason, it's not a bad idea to only buy gear for which you can get a schematic.
