Here's my story with a UMC-1
I recently purchased an Emotiva UMC-1 , XPA-5 and a XDA-1. The amplifier and DA converter work fine, the UMC-1 on the other hand have been plagued with all sorts of problems. The first one had no sub woofer output, either on the balanced output or the RCA output. When an IR receiver was plugged into the rear IR input it didn't function at all and locked the unit up. To get the unit unlocked I had to unplug the main power cord to get it to function gain. I contacted tech support at Emotiva, here both the tech and I figured it would be faster if the sent me replacement boards and I would install them. This I did, it solved the IR issue but still no sub output. So I called tech support again, this time a new unit was to be sent out. I requested that the unit be burned in and that all functions be tested. When I received the unit the burn in I request showed no evidence of being done. There were no marks on any of the HDMI connectors, binding posts or even the main power cord. This could be a go thing I thought, a brand new unit was sent, not a B stock. After removing my Denon AVR for the second time I connected the UMC-1, I have subwoofer output! I then set the system up using my RTA and once satisfied decide to play Avatar from the BluRay. Here starts more issues with the UMC-1. Now I'm getting digital pops, clicks through the speakers! So I try different settings, PLII, Dolby Pro, etc, all have these pops, clicks coming through. After spending a lot of time trouble shooting I determined that it is the digital processor causing the problem, because if I go direct or stereo mode there are no pops present. The noise comes from all my sources, Apple TV, BluRay, media server and cable box but only when using any of the digital processing. Once again I contacted tech support, via email, I received an automatic response saying the email has been received. A couple of days later and my frustration level increasing, I call and was told the techs have received the email and they are working on it. To help with being clear on the problem I record the noise and send it to the techs, still no answer back. I call again and get the same answer, the techs are working on it! So now it's the weekend back goes in the Denon AVR which has no noise problems and so I wait.
Did I just waste $500 + on a processor?
