Big difference between HDMI and coaxial soundtage

[rossco]

Hi everyone I've been experimenting a lot with my coaxial connection output and HDMI. Huge difference, the HDMI has all the clarity detail and a much more apparent and larger soundstage, also the imaging seems to work better too.

Coaxial sounds good but the soundstage is wider but seems like there's the centre imagine is lost compared to HDMI.

With coaxial the extreme lows and extreme highs seems better by about 30 percent and I can hear the space and atmosphere around the instruments (especially cymbals or acoustic guitars) better.

Any other want to chime in on their experiences ?

If the source material and processing are identical, this is highly unlikely. How did you perform your experiment and test setup?

None of this is possible if your setup is working correctly. What gear is involved here? What media are you playing?

Are you sure you're sending the same bitstream over both interfaces?

Way too many variables unaccounted for here for this anecdote to be terribly revealing.

Hey guys I just realised lol I wasn't proceeding the audio in pure direct mode so there was a bit of background processing going on.

When I tested it in pure direct mode between coaxial and HDMI they were very similar actually.

So I recorrect myself.

* I'll say this the HDMI proceeding on a high quality receiver, man it sound freaking awesome and this is comparing to my Denon PMA a11p which is dual mono balanced differential.

With mercy, that.

LOL surprised to see this sort of post on ASR. So how did you level match? Or do the blinded comparo?

I have a class 1 acoustic test mic connected to audio tools apps (sound level meter pro). App employs ANSI and ISO filters.

To that's a good observation mate, there's always a difference is perceived volume and frequency as indicated by the fletcher Munson curves (forgotten what the updated curved are called).

Doesn't answer my question, does it?

I think you might have missed the post where OP realized DSP was active on one of the inputs and the issue was resolved...

I should add Iam new to here and kind of realised quick that people like clear, detailed specifications in posts, so I'll keep that in mind when posting again. I think it's a good idea
But maybe go easy on me just this time.

Didn't see that, but his answer was after that so.....

Yes, thank you. I re-corrected my clumsiness lol

Yes, thank you. I re-corrected my clumsiness lol

So the corrected statement is what particularly?

Give the guy a break guys, we've all done and posted stupid things. Welcome to ASR @rossco, we are pretty diligent critics of stuff that passes for truth on a lot of other forums as you've discovered. It's worth it, trust me and your brain and wallet will appreciate it even more.

So, now you know why we so diligently ask for details. Details matter, a lot!

You still haven't given us the full story, though. Now we find out that an AVR is also involved next to a stereo amp, it seems? That's a whole new can of worms, and some of them might actually taste good Please detail your setup a bit better, and tell us what your goal is with this.

As to level matching with a dB meter, this isn't generally accepted as good enough for level matching. It's just not accurate enough. A better way is by using a DMM and measuring the voltage at your speaker terminals.

Yes, thank you. I re-corrected my clumsiness lol

Hey, kudos for figuring out the issue. DSP is certainly one of those things that could actually be causing an audible difference in electronics!
