Hopefully you can hang around a bit. There are some smart people her, along with a few smart-asses, but all in all, a great place to hang out.
(pair of) SILVER-7 TUBE AMPs

On another forum, one respondent warned that if the amp fails it may output DC ("go DC") and destroy the speakers. I've read about this risk elsewhere with the old Phase Linear amps, but does this risk exist with the Sunfire Sig. 600? If not, please explain why not. Thanks!
I would not figure the risk to be any more to those speakers than any other, but that's just my opinion. BTW Welcome to LA LA land!!!
I like the DMT 12's. Had a pair I worked with many years ago. Great point source monitor. I currently have the 8" version of those which were at CF last year.
One other doubt I have. I'm looking at lots of used amps. Many of the better ones have THD readings around 0.05%. While the sunfires seem to have universally good reviews I'm surprised to see THD listed as no more than 0.5%. I know spec sheets of some companies are to be taken with a grain of salt but other audiofile amps like the McIntoshes have much lower levels. Any explanation?
If Bill Flanery replies, I'll report back.
Cheers and thanks again.
No, have not tried bi-wiring. No reason not to. The crossover is complex enough in the typical Tannoy I'm not sure how much you would gain.
At CF I was running a 6C33 tube amp thru Red Rock Audio cables.
I'm not a believer that you help yourself having monster power amps when it can't possibly be used. I've even heard such a situation and on a more efficient speaker, a good amp may actually sound like crap. I have no idea how the Sunfire would sound in this situation. Others will no doubt speculate.
The Tannoy's (you have experience and probably knowledge of such) have complex enough typical crossover, that they often are run with more power than the listed eff would suggest.
The single THD number is a bullcrap spec. Meaningless to the extreme. Tells you nothing about sonic sound quality. Takes a much deeper dive into specs to get a hint from them as to sonics. And in the end, they tell you more what is wrong, not right so much. IMHO.
Another doubt I have about the sunfire. I read in various posts about people sending their amps to very specific people for repair and that circuit diagrams are held by a select few. I live in Brazil and won't be able to send my amp to the states if something breaks. Do you think I'll be left with a lame duck if the amp needs repair, or are these amps pretty simple to fix by a good tech?
