How am I frying all my amps? Oscillating? Help
So I think my next step is a new equipment purchase. I'm thinking I will buy a consumer grade 5-disc changer with variable output that I can hook right to the Classe. And I can use it outside in zone two later.Without touching anything else, hook ... 
How am I frying all my amps? Oscillating? Help
I plugged everything into the one PS Audio Quintet (not UO). Every 3-prong cord got a cheater plug except the preamp (Cary Cinema 11). I have not taken out the Goertz cable because I want to make as few changes as possible at one time.Using shorti... 
How am I frying all my amps? Oscillating? Help
I will check for DC at the preamp on Sunday. How does one measure an XLR output? Both pins, one at a time, to ground?Atmasphere, I'm confused as to what your final opinion is on whats wrong?Thank you everyone! 
How am I frying all my amps? Oscillating? Help
Atmasphere, no other components were plugged in during my testing, digital or otherwise. Just the amp. So it can't be a ground loop, right?I've had a ground loop before. It sounded like a loud hum/buzz. The noise I'm getting is a "wavy/wiggly" squ...

Tobias, if I has an oscilloscope I would test the pre. One of my customers has dozens of them but I don't know if he'd let me borrow one.I would be most interested to hear from Krell now too. They've had the amp for three weeks and only promised t... 
How am I frying all my amps? Oscillating? Help
Atmasphere, I had done these tests with the Krell before it exploded and I did the same tests with the Classe just now with equivalent results.The scenario:1) Amp plugged into wall. I tried all three dedicated circuits.2) Nothing is plugged in exc...

Alright, I guess the Cary goes to the dealer. And I'll pull the Goertz temporarily as well.Don't you guys think the Classe is already shot? Or will it recover because its own protection circuitry says nothing is wrong?_____Dave_b, how does a guy w... 
How am I frying all my amps? Oscillating? Help
Reb1208, Gs5556, can you explain how DC from the pre affects the amp? Why would the amp care what signal it amplifies? I'm not arguing, just not understanding.Gs5556, how does DC come from the wall socket? Or do you mean the UO?Jsd52756, the lines...

^ should NOT be an issue 
How am I frying all my amps? Oscillating? Help
Newbee, thats the other way around. Goertz cable causes oscillation because the wires are so closely spaced together that they have very high capacitance. Still, this should be an issue with Zobels and these particular amps from what I know.Maybe ...

Ait, just plugged the polarity checker into the wall outlet and the UO outlet. Reports polarity correct. I've wired my entire house and numerous others and been through state inspections. We can call me an electrician. 
How am I frying all my amps? Oscillating? Help
Tobias, what is this simple test of an outlet?I just broke out my Fluke MM. The voltage at the wall is 123.0. The voltage at the power cord to the UO is 123.0. The voltage at the outlet end of the UO is 123.0. The voltage at the power cord to the ... 
How am I frying all my amps? Oscillating? Help
The Adcom was plugged directly into the wall. The Krell was plugged into the wall for half its life. Can't see what a functioning line conditioner can do to an amp, either its getting non-shorted power of the right voltage or not, right? And I ran... 
NAD M5 vs Marantz SA-11 S1 or SA-14
Thank you both. The Ayre, Krell, Esoteric, etc are too pricey for me and I won't buy anymore Cary so Marantz and NAD it was. I like the looks of the NAD more and it does multi-channel too which doesn't hurt in the long run.Someday I may even have ... 
Rewire Marantz or Reterminate Cable
Thank you for confirming that Reb1208.
