Bel Canto left channel cutting out with distortion

I am hoping someone can give me advice in regards to my Bel Canto eVo2i GenII integrated amp. I bought this amp used about a month ago and for the first couple weeks it worked perfectly. Last week I changed all my cables, and for the first time, hooked my CD player up using Balanced.

At first, I did not have any problems. Then one day while doing some listening, out of nowhere the left channel cut out and became heavily distorted. At first I thought it was the tube in my CD Player, so I replaced them. No fix. I made sure the speaker cables were secured and tight. No fix. Then I unplugged the XLR from the back of the amp, and plugged it back in. It began to work again... This occured about three more times within a few days (The problem seemed to be resolved after unplugging/replugging the cables multiple time), then worked fine for a week straight.

The other day it went out again, and is out for good. No matter what I try it will not come back. The reason I think it is the amp is that if I switch the L and R cables only at the amplifier end, it always stays in the left channel. I know for a fact the right channel from the CD player is working, because it works in the R input on the amp. So this must be an amp issue right?

Also, since this has been happning. When I turn the amp off using the rear switch (Not standby) there is a huge thump/pop when turning the unit back on. I am afraid it is going to ruin my speakers. It never did this before...

Any info on what this might be? I talked to Bel Canto and they quoted me over $900 after shipping and labor to replace the Amplifier Board (if this is the culprit).

I live in Orange County, CA. Are there any local techs that can solve this sort of problem?

I definitely love the Bel Canto. The sound is very hard to describe, it is so much different than my previous Portal Audio and NAD amps. I don't notice the excessive detail or recessed midrange, but perhaps it just compliments my Sonus Fabers. One thing I love is its neutral characteristic. It really forces you to pay attention to the source component.

If the amp can be fixed, it will be staying with me for a long time.

Wireless200, the new S500 and REF1000MKII are quite different from the earlier tripath based Bel Canto amps and a little different as well from even Bel Canto's first generation of IcePower amps such as the S300 and REF1000. The lastest amps, such as the S500, are quite dead neutral, in my opinion. I find the S300 and original REF1000MKII are ever so slightly warm of neutral. There is definitely good power on tap with the new amps. I haven't noticed anything in terms of recessed midrange, so I'm thinking it may be the recordings. The very first generation of tripath amps by Bel Canto, such as the eVo200.2 definitely had a bit of a recessed midrange, but I never noticed that with their newer amps. If someone hears that though, I respect his opinion.

Disclosure: I am a Bel Canto dealer, so feel free to take my opinion for what it's worth.

"I've always had a soft spot for this piece. As a dealer I've had opportunity for a lot of different pieces to listen to in my system, but I always felt this one was special and that's why it was a stable piece in my system for quite a while(especially Gen II with the capacitor upgrade)."

I agree, I love my eVo2i II...I auditioned other integrateds in the price range including Plinius and Perreaux, but the Bel Canto just did it for me. The 3D soundstage, neutrality, dynamics etc. (and that these characteristics are maintained even at quieter volumes, unlike some I have owned) ended my search.
