OK, thanks guys. I will take it up with them and see how it goes. It's just a royal pain and sure seems excessive. 2 amps in under 5 years? I'm happy with their service so far and happy with the rest of speakers...(I have two rooms with all Axioms in 5.1 M-80's VP-150 Q-8's EP-600 great room and M-22's VP-100 Q-4's EP350 bedroom).....but this sub has me thinking of changing to something else. Love it when it works but having to worry about it....again....sucks.

Do you guys leave them plugged in all the time and turned on? I have always done this and never thought twice about it until now. I bought my old M&K 350 almost 20 years ago. It's been moved through 3 houses and across the country and always plugged in and still works flawlessly. This EP-600 has been in the same spot since day one and seems to be biting the dust again. Roughly 2 years to each amp. Bummer.

Just seems really abnormal. Wish I had a definitive cause.

I leave my sub plugged in 24/7, it's not an Axiom sub.

Robert, Axiom hired Andrew Welker(former Mirage/Energy head engineer) earlier this past year, and improving the sub amps was one of his main priorities. I too, would contact an Axiom representative and ask for the updated one.

I hooked a Kill-A-Watt up to my system and checked the standby power. I figured 28 Watts was a little high, but for a TV, receiver, PS3, and DVD player, plus two subs it didn't seem that bad.

But when I turned off the hard power switches to the subs the standby power was 0.8 Watts. Yeah, I turn my subs off now.

Not Axiom subs, but I understand this is a common thing.

Thank you Adrian, good info.

I went through 2 500 amps in the space of a year and am on my 3rd. I think they were having issues and there were personnel changes - it seems to have smoothed out now. Definately pursue the issue with them. I believe Axiom will make it right.

Wow....that does seem like a big standby draw. 27 watts just sitting there? Curious....Wish I had a way to test this.

Oh..and I leave mine plugged in and on 24/7. I believe that I remember reading somewhere in Axiom's literature that the amps are designed that way - they go into sleep mode in absence of a signal then wake up when a signal is received.

Great, very cool, thanks Argon. Just the kind of info I was looking for! No I don't feel so alone.

BTW...did you have any hot electrical smell coming off of yours? And is it working fine now?
