+1 for trade in program. Does he do it?

This is his response from my email about a week ago:

 

I'm considering a trade-in program for the new UHA760, although I
don't know what the details would be yet.

I could find no room for improvement with the 6S sound quality, really. At least the amp section. I feel the additional features alone are worth the extra expense. So if SQ remains the same (or better- who knows!) I would be satisfied.

I am curious as to what opamps this will use, as the blog entry suggests they will not be socketed. The follow up unit will have socketed opamps. I'm hoping 8610..?

My amp randomly makes LOUD buzzing noises, which would change in intensity/frequency if I moved it around. I emailed him at the website and got no response, anything I should do?

 

Also, it was purchased Jan this year so it's still under warranty.

ADA4627 please :D. Though I'd wait for the spdif/socketed version cause I mainly use it with my dx50.

Nick doesn't answer emails on weekends. Did you check if it was your other components causing the problem?

Yep. It makes the same noise from iPhone LOD, USB, and 3.5mm in, on anything.

 

Had it hooked from laptop < Leckerton < Speaker Amp < Speakers and still same noise.

What op-amp are you using? Some op-amps are super prone to interference.

I hear no noise no matter how I hook mine up. It sounds like something may be wrong with yours.

That would explain it. That opamp is very susceptible to interference, order a pair of ada4627's and you'll get better sound and no interference.

Yep, got a email reply today saying it's electrical interference. 

 

Dang it,  100% of the time I'm using the amp, I'm near a couple of laptops and phones..

Yeah. I guess only option for you would be a low interference op-amp. Ask Nick which one has lowest interference.

New amp details sound pretty awesome, but man is it expensive. I had already decided I would be getting one of these when they come out, but at that price point, I might wait for reviews or for used ones to become available.

I hear a loud pop noise through my amp when there is a nearby camera taking a flash photo. It happens with my Canon EOS 450D and other cameras. I'm using the OPA209 opamp.
