Thank you, Dennis.
Though these boxes typically don‘t come with a PSU. Mine didn‘t.

Though these boxes typically don‘t come with a PSU. Mine didn‘t.
I have this one (looks similar but no HDMI) and it came with a PS. One of the commenters in the review section changed his zero star to 5 stars after the tech support convinced him to use the original PS.
I just compared music from this adapter to the same music but direct from Roon and couldn’t tell the difference. Much better than I thought.
It does make a difference - switched the no-name 5V / 2A USB PSU (like an iphone charger) for another no-name adjustable 3-24 V / max 6 A / max 144 W PSU (not targeted at battery charging) - et voilà!
happy camper again - thank you guys!!
I got an inexpensive universal power supply from Amazon that works like a charm with this HDMI audio extractor. It can be configured to output V, 4,5 V, 5 V, 6 V, 7,5 V, 9 V, 12 V, 2 A, 30 W and never had a glitch with the combination of a Sony UBP X-800 M2, this HDMI audio extractor plus the power supply and an SMSL DO 300EX.
I own two versions of it, the I2S plus SPDIF DoP one and the cheapest unit that can only output DSD vía I2S which is the one I'm currently using as with my DO 300EX has no need for DoP.
As I said earlier on this thread, despite the SMSL DO 300EX has two ways to reduce jitter, one is its own clock (CK-03 I think It's called) and a second order PLL jitter reduction, and that none of them work with either the I2S and USB inputs, only with the S/PDIF and TosLink inputs, I prefer the sound of the I2S output/input despite the jitter this HDMI audio extractor may induce.
The SMSL DO 300EX uses the AKM 4499EQ (it's a two IC's solution, one IC does oversampling and Delta Sigma modulation and the second one does the actual D/A convertion) that doesn't mention on its specs any means of jitter reduction, unlike ESS IC's that do tell they have a jitter rejection feature. AKM seems kind of secretive when disclosing the full specs of their D/A IC's unlike ESS.
I prefer with both versions of this HDMI audio extractor the sound of the AKM based DO 300EX to the sound of the ESS based DO 300. I've had them both at the same time connected to my set Up (Marantz PM 6007 integrated amp plus KEF Q-550 speakers) and the AKM DO 300EX sounds more natural and analogue-like that the ESS based DO 300 which sounded analytical and cold. And both of them sound equally resolving, getting plenty of detail out of my digital media (some think AKM chipsets sound warmer at the expense of detail and dinamics, that's not my experience) and very dinamic.
What I like from this HDMI audio extractor is that fills in a gap in an inexpensive way, and that is the capabilitiy of matching the SACD player/transport one wants with the D/A converter one chooses depending on budget or chipset preference.

I have one question regarding this HDMI audio extractor. Up to what resolution is It able to pass from HDMI in to I2S out?
Has anybody tested it with DSD 128 and DSD 256?
The Sony UBP X-800 M2 is supposed to play Up to DSD 128, but when I try to play some DSD 128 files either from this HDMI audio extractor or straight to a friend's A/V receiver that can play up to DSD 256 via HDMI, the Sony UBP X-800 M2 plays DSD 128 files, but It outputs PCM 176.4/24 and not native DSD 128.
