HDMI for only audio to AVR?

[Fahzz]

I currently run LMS from a mini PC through an SU-1 DAC by USB to a Denon AVR 4800 running Audyssey. Will it have any effect good or bad, to just use an HDMI out from the PC to the AVR for audio only and skip the outboard DAC? My thinking is that I don't need an "extra" conversion to analog??? Thoughts appreciated.,

I have no idea what LMS is but not sure of your connection. Generally USB into an avr is only good for mass storage device but would be fine otherwise. HDMI would give more audio options. Skip the outboard dac, just not needed and if you are using any processing in the avr, a moot point.

LMS is Lyrion (Logitech) Music Server. The connection from the DAC to AVR is analog RCA cables.

"Skip the outboard dac, just not needed and if you are using any processing in the avr, a moot point."

That's what I was thinking, and something I never thought about.

Have no idea what that is or what its limitations are but haven't looked it up yet which would probably answer those questions. Did you?

AVRs generally do a adc conversion for processing.....

Perhaps you've just read too much of the silly side of audio literature

Thanks. I consider asking my inquiry on this forum to be "looking it up". Anybody else have a response to my original question that doesn't feel the need to be condescending?

I think it is likely that going straight HDMI into the AVR will get a better result than having the extra DAC, and ADC within the AVR in the chain. Depending on the AVR, the HDMI jitter may be high, but likely still better than having that extra DAC & ADC.

Thanks. I was looking for some affirmation. I'll give it a try.

Why not? I use HDMI from a blueray player to play only audio formats like cd/dvda/sacd into my processor. What's the difference?

Yeah go for it, you probably won't experience any noticeable difference.

And, like I do, just ignore the members here who seem to participate for the sole purpose of being contrary. Life is too short to be bothered by such... people.

Pretty use the Denon AVR 4800 has a "pure direct" or analog passthrough mode, but if using room correction there will be an ADC/DAC step.

Probably won't be much if any difference though, as the whole chain is limited by the distortion and noise floor of the amp anyway.

Forgot to mention I'm using an outboard amplifier through pre-outs. This HDMI thing is just another tweak to try.

What motivated the "looking up", though? I'm not being condescending, just trying to keep it within reality.

What makes a "tweak" worthy to begin with?

This is a review and detailed measurements of the Denon AVR-X4800H 9.4 home theater receiver. It was kindly drop shipped by a member and costs US $2499. While the look is the same as previous generations, the feel of the control knobs is much improved which I appreciate. Menu system is also...

Thanks. I read that review a while ago. Nice to see the HDMI Measurements.

Thanks for your help.

Thanks for your help.

You're not looking for help apparently, just affirmation of silly tweaks....

Will you have a TV connected to the Denon? My experience is ARC has tended to interfere in a wonky way. Not undefeatable, but definitely annoying.

I messed around with HDMI but I was getting video on my TV screen from the streaming software, which I don't want because I already have a small touch screen for that. Instead, I found an SMSL PO 100 that takes USB signal from the PC and coverts it to SPDIF, and I send by coaxial cable directly to a digital input on my AVR.
The result is I got rid of a redundant DAC, and maybe can look into multi-channel audio later.
