Erik, you may want to just try using the lossy form of DD/DTS. It may actually come out better than 7 channel LPCM over HDMI. I have tried LPCM on my system and it works, but it doesn't actually sound quite as good as DD/DTS. Oppo is having to attempt to clock PCM at 48khz over HDMI, which de-clocks the signal anyways and sends a PCM block over multiple HDMI packets (which run at a completely different clock speed). The clock timing gets all messed up. If you use compressed DD/DTS, the AVM50 will un-wrap the data and then properly clock the decoded information at 48khz.
Just purchased an Anthem AVM 50 to Frankenstein with my Luxman 507
I’ll be posting notes here about how this goes.
The overall goal was to add HT without breaking my 2 channel setup. It would have been nice to add full 4k HDMI switching but all those options which I liked were $2,500 or more. I got the AVM 50 for $650 + Tax.
90% of HT I watch is streaming, so audio quality is usually limited to DD+. I can output DD via optical from the TV and I can use the TV act as a 4K switcher. I can hook up my Oppo 103 directly to the 5.1 inputs. The AVM 50 will feed L&R to the Luxman amp directly, and all other channels go to 120 W Class D amps that have been collecting dust, plus my sub via XLRs.
Audio I can’t see any negatives, but there are a number of remote steps which need to happen.
For another $2K or so I could have gotten 4k switching (which apparently is unreliable in several brand of receivers) and saved myself step 1.

- TV - Select source
- Luxman - Click ’separate’
- Anthem - Volume
