I can relate to your frustration. My story was flawless playback from my Altitude 16, then suddenly I got an buzz/hum and from an AppleTV, some ticking sounds. Tried everything, pulled cables, replaced HDMI cables, disconnected devices from Altitude and amps...literally everything in 3-4 days of troubleshooting. Called Trinnov and they were great in trying to help me
- both Antoine in Paris who ran diagnostics and Jon Herron & Pete Carpenter in the US. They even had me send it to CT so Pete could check it out on the bench. They found nothing wrong in 4 weeks of checks so they returned it to me.
But...during its absence I accidentally discovered that Comcast had done a lousy job putting in new wiring to our house (they left wiring & connections open to the air & outside the enclosure box so exposed with a jumble of cable spaghetti) when they had run a temp line across to our neighbor due to lightning damage to the head box that fed our house. I cleaned up their cabling mess (in disgust) before getting my Altitude back and to my delight all noise was gone and back to normal! Put everything back exactly to what it was & to this day, noise hasn't reappeared.
The moral of my story:
1. The Altitude has delivered flawless
audio and video pass-through and continues to do so after 1.5+ yrs of ownership.
2. Trinnov support had been fantastic! I've never experienced this level of support from any other audio/video company. They will go to great lengths to help the end-user.
3. System & setup issues, totally unrelated to the "symptom", can be the real fault, very difficult to find & fix. It was luck on my part that I found the culprit - probably poor grounding or some cable issue in the temp line Comcast ran across our yard, between our neighbor's driveway & street (could have been crushed, causing a broken cable shield?) I blame it on Comcast since there was absolutely no changes in my setup, gear & cabling when there was no noise and when there was noise. And back to no noise. The only difference was >> Comcast.
It's a shame that in all the troubleshooting you, your installer & Trinnov did, couldn't find the problem. I have to believe it was a system/setup issue since it happened with 2 Altitudes & a Storm...very unlikely that 3 new units would be bad.
In the end, it's great that you're happy with the Monoprice and delivering great AV enjoyment! That's what counts.
