According to my reading of the issues with HDMI ARC, it seems like the issue had to do with (inadvertently) sending encoded audio. As long as the TV and any other sources are sending their audio as stereo PCM, it should work fine.
I had the 760H for several years. I bought it from Costco, and at the suggestion of Denon tech support, was able to take it back to Costco and swap it for another unit. It drove me crazy! Frequently going into protected mode. I lost count of how many resets and other efforts to get it to stop doing this. Yes, when it worked, it was okay - many connection options (automatically selected according to which input you select) - sounded good. I found Denon tech support of no help to me. Seemed like what I was hearing from them was send it in (at your expense) and we'll take a look and ship it back to you (at your expense). I looked at forum remarks and many reviews. I found that what I was experiencing did not seem a one-off. I finally junked it and got the WiiM Amp Pro about a month ago. I am MUCH happier.
I have the idea that one can use the USB port (with a USB to 1/4" adapter cable) to feed headphones? curious: what USB type is this? (2.0, or what?)
They can be used for audio output to USB DACs or DAC+Amps.
USB 2.0 Type-A
They also function for digital audio out, which is exactly what USB headphone adapters (portable DACs) do.
I'm not disputing that part.
Not a good idea to use speaker-level subwoofer connections on these class-D amps.
Why not, and is that limited to Class D chip amps or does it extend to Hypex et al?
I speak only for these TI/Infineon/etc. chip-based class-D amps; not sure how the discrete class-D amps like Hypex/ICEPower/Purifi would do. My dad attempted this with his Rel sub on Fosi V3 Mono and it was SO not happy.
Thanks for the reply - I have my Emotiva sub connected via speaker level from my Hypex NC252 (Buckeye) and have had zero issues.
What happened? Did something break or was it a noise / sound quality issues?
Does the WiiM volume control alter the volume via USB or is it fixed?
After doing more research on the WiiM, it also uses a bridged output, and the “-“ terminal is not ground. I’m exploring how I could use use stereo L/R subs with the WiiM. Doesn’t seem like this is possible.
