Today I tested this unit, which is supposed to convert HDMI audio digital to coaxial audio digital.
I only have one player, a cheap $35 DVD/CD unit that I bought in Aliexpress. I just bought it for my wife to play our CDs, as I normally use my Ethernet network.
Well, the player has an HDMI output, and the very same unit was used as player on a YouTube video, comparing to another CD very expensive player, both connected to the same $11,000 DAC. The DAC had HDMI audio digital input, so he could connect it directly, which mas Topping DAC has not. So I was stuck there.
On the comparison video, the person was hugely surprised that the audible differences between both players were absolutely minimal and non important. So I went looking for a way to convert HDMI to RCA coaxial.
Well, I found the one above, and it worked! I do have audio using the adapter, and the question is audio quality.
I wonder if amirm can test this adapter, which is very cheap and should be easy to get a loan from AE.
It might be a solution or an option to many people that have an HDMI output on a BD player, a regular one with video and all, and use the BD player just as transport, and see how it works out.
My results with this HDMI to RCA digital: the sound is quite sibilant and plays more detailed highs than the player analog outputs. Now, the player's analog output are not that good, even if they don't sound bad. Internal DAC and analog outputs are probably the reason, and it's not worth it to work on it to modify that.
I thought the RCA cable between adapter and DAC might have something to do with it, and I tried a different one. No difference, same sibilance.
OK, now come further surprises, which I didn't expect. This time I connected the player's HDMI output, directly to the Pioneer receiver's Games HDMI, which of course has its own DACs inside. Now, there seems to be an improvement. The sibilance was still there, but much much more attenuated. Now I can't say if the CD was not recorded that way, or if the treble frequencies (can't say starting without measurements) are being altered by the player.
Another thought: what if what is introducing the sibilance is the HDMI output, the internal electronics? The video signals wiring on the cable might not be affecting the audio? The latter is rather unlikely, because all BD players send video & audio through HDMI.
There's an Amazon box that is simpler (and double the cost) than the one I used. Amazon also sells a box that is similar to the one AE sold me, brand name CAMWAY.
But it only has audio functions, no video outputs. Maybe the video wiring is disconnected internally.
Once again I would appreciate to have amirm suggestions on how to go about this issue. CD players and discs seem to be resurfacing.
