Oh yea, and a "shoot the terrorist bastige day ... "

B&K made a nice amp. I used to have one (the deluxe st 100 with better components in it), but it wouldn't drive my Maggies very well. (4 ohms, 86 db efficiency). I traded it in on a Classe CA 300 (600 watts into 4 ohms), and got a lot of value for the B&K on the trade. At 105 db the Classe runs slightly warm.
B&K and maggies ... what's with B&K and maggies ... that's exactly how this poor beast met its maker. He drove maggies playing jazz. Apparently it was not loud enough, so he cranked it, and poof went the amp.
Anyway this is a B& avr 507. I dunno about yours but this is frucked up by design. Turning it off with remote ... yes that's like hitting mute, it leaves the amp powered on, only shuts off input. What ... yea ... that's powering it off for them. Stupid.
I have atleast 1 pair of fried smoothing caps (yes coke can sized screw top caps costing 70-80 bones a piece ...) plus atleast 2 output transistors.
Classe stuff is good, but no matter what equipment you got, I'd put em on a monster 5100 or similar power conditioner, and turn that sucker off atleast nightly. I dont believe in amps that go to standby when you turn it off any more. I think its a design flaw when the amp stays powered up, when you say off.
They power on in 3 stages so your lights dont dim when you switch on ... but when you say off ... it means OFF.
BTW My carver 7 monoblocks when you turn them on, not only do the lights dim, they actually killed the 15 amp breaker in that room ... had lots of trouble with that one in the past, its maybe tripped off 10 times in 10 years, and the rest of my house not even 1-2. Anyway those guys worked like a circuit fault finder. I had to run to the store get a new breaker and swap it.
Cool.
