Even though I only got it yesterday I'd like to try a regged psu at some stage just to see if it improves the analogue out. I've been running it constantly and it has improved, I'll give it a week before any serious listening . So far its quite behind my diy dac (just my opinion) but it sounds decent .
I noticed selectable filters for the analogue out

Remember there is a negative rail too. The embedded SMPS just does the +12v. There is an IC TPS6513 that is a dual rail buck converter

Interesting snippet from another thread by mikessi.
"So I did manage to get the bass section of the Linkwitz Orions set up as dual-mono subs for the LS50 Meta. Wiim sub out>phono splitter>amps>dual Orion woofers -- a pair on each side. The EQ for the Orions bass was replicated using the PEQ function in the Wiim Amp. I got it pretty close to the original EQ in the miniDSP.
The end result was a much fuller sound and deep bass with the LS50 Meta. I tried a variety of crossover frequencies, from as low as 80Hz to as high as 150Hz. Best seemed to be 120-130Hz. It was quite a nice tidy pleasant presentation, but a bit too tidy at times. Switching back to the Orions always brought a sense greater relaxed openness, fuller range of harmonics (??) & authority. That switching was only done a couple times because the process was rather fussy, a PITA."
I was going to ask about splitting the SW output for 2 channels (mono I know) and it sounds like it is feasible

A new internal PSU would be my design goal but then I would need an Ultra myself. I almost had one but its was sold out apparently.
If someone can measure the negative rail that would be nice. I take it is -12V. An aluminium bracket with a new PSU could be a nice modus operandi. External stuff is like adapters/wall warts: a pest. Not the adhesive tape/melt glue/iron wire/air acrobatics Fast Freddy type myself so I would definitely go for well designed and mechanically sound solutions. Space wil be enemy.

It must be -12v according to the Teddy Pardo PSU. The pos rail uses a Tps7a4701 so not much improving the regulation of the positive.
TPS7A4701 is good.
Since I do not have an Ultra people that do have one can measure internal space. I can draw a PCB for a Talema 25VA transformer. It all depends of available space and it sure is tight seen from pictures. When an internal PSU is absolutely impossible then I would not choose the Ultra 😉
Another option as said before is to make a replacement board for the Mornsun but now with AmyAlice filter and mounted upside down.
It will definitely be a trade off situation. Anyone looking for a “best possible” solution will run against a concrete wall I think. The Teddy Pardo PSU can be good but it should be as it costs more than the Ultra. Total cost is then higher than the Eversolo I think which makes it a less optimal choice alltogether.

don't think you'll get the talema in there so would have to have external supply like teddy Pardo or recase the ultra
there's enough space for the amyalice

A 15VA and a 7 VA perhaps? We need to know actual worst case current draw of both rails.
The Mornsun upside down with AmyAlice can be done. Can be small. Then we again need all 3D dimensions. Please remember I am driving in the dark without lights.
Recasing the Ultra is a step too far IMHO. In effort and in cost.

By all means guys use the USB out to a good DDC it's a notch above the internal spdiff out.
The clocking scheme on the Ultra is definitely lacking.
I don't think messing with the internal power supply will make things better for an external dac but will probably help for the internal one.
The SMSL PO100 pro that cheapaudioman raved about s really good for the price but there is a hidden gem on Ali... that easily takes first place over all DDC's I tried out including a modded Singxer F1 .
It's called UAC1digtal interface. It utilizes good clocks, has spdiff and I2S via HDMI out.

If the clocking is not done right, PSU needs replacement and still an external reclocker and DAC are needed I will not put time and energy in this device. It is then like a cheap car with extra better external engine, an added fifth wheel, gold plated gear change knob and solar panels on the roof. Wiim Ultra seems very good for the price, no more no less. Quite satisfied with DMP-A6. Different price, different class. Not even opened it which is a first.
Don’t listen too much to youtube influencers. They create income by hyping stuff and you are ending up with 3 mediaplayers and 5 DACs per year. All mass produced rare and unknown hidden gems, in reality the majority being disposable throw away stuff.

Understand your point.
I needed a Streamer anyway and found the Ultra with its room correction function for my environment the ideal option.
All my gear is in a sideboard so visible appearance and number of components is a no issue for me. All that matters for me is the final sonic result.

If the basis is good a most useful aspects then it pays off in fun and results. My system is to want Mercedes quality for a Fiat price, not to have a Fiat ending up for Mercedes total cost.
No chain will really be better with a cartload of devices each with clocking, PSUs, possible mismatches, design quirks etc. whether one can see the setup or not. A better approach seems to have a real good device alltogether without the need for extra bells and whistles.

Thank you! Regret to say it but the Ultra is a tad too small. It is pretty impossible to build a linear PSU in it. The upside down switcher with filter may work out OK.
Next weeks custom one off jobs enough so I bail out. Sorry.

Mercedes quality with ES9038q2m and datasheet OPA1612/1656 output stage will not happen. I got exactly that in the Ultra and I doubt that the Eversolo sounds different. It delivers a clean precise somewhat dynamic sound or may I say wall of sound.
With good discreete opamps it will sound much more dynamic with noticable layering, and more detailed.
The Chinese R2R dac souds more spacious with a soundstage extending beyond the speakers, has more depth and sounds more natural.
Noise is a no issue now since I reactivated my stepped attonator.
Btw. My Ultra with DDC, R2R DAC and discreete opamps is still below the price of the Eversolo.
You can’t doubt that without having both side by side to try out. BTW the Eversolo was 700 and it is one (1) device. For more than double the price it should be a better device somehow. It offers an M2 slot, balanced outputs and relays for muting which are all nice. I haven’t found the need to open it or change things. I just would have liked AKM inside as ES9038 is not my friend.
I doubt the perceived quality of a low cost chinese R2R DAC to be honest. Could very well be an effect generator with effect generator opamps F0r Äüd1O but we will never know as it is not measured.

having removed the switcher supply am getting good results with using a supercapacitor, so will stick with that instead of a linear supply
