Was it a double blinded test? If not, I find it hard to believe what you and the other test results.
Yes it was a double blind test

To me if certain DACs were excluded from tests it is not a fair test and shows bias.
I didn't find their methodology on a quick look at the thread, but where do they detail how this was tested? How is the double blind being done, and are these ab preference tests or something else?Yes it was a double blind test
ALLO SHANTI psu spotttedHi ,
we are developing a LPS with dual 5V output, it should be out in a few weeks. Yes you need 2x5V PSUs for best quality . Yes we include only one PSU

It is hardly necessary, they built it and tweaked it for lowest noise for the people who are interested in buying cleaner power. Amir has already proven several times, LPS is hardly necessary/waste of money since a proper design should already be filtering the incoming power to a certain degree. ALLO can still make it as long as people want to buy such a product though... as long as it is a competent design and not a noisy psu the likes of iFi power, I still respect them going through the R&D to create a proper engineered product:RPI based audio equipment is supposed to be cheap and now you need a 169EUR PSU?!?
^^^In their own testing there was a tiny gain. Worth it? Probably not but that's up to the spender... I would certainly not spent 160EUR on 1.5dB SINAD/THD+N but someone else might.In fact , by using the LPS , we can see THD+N gets better by 1.5db

First a capacitance bank (massive) to reduce the 50/60Hz noise, then an active filter, followed by an LDO to keep voltage stable. Since LDOs have poor transient and impedance, we used a last active filter (with good transient) and then capacitors more than 15.000uF but most importantly, super capacitors on the output. Final power comes in fact from super caps...
Seriously dude you are too arrogant for your own good. Also it is "its" accessories, not it's, for all your condescending tone is worth. Whoever said anything about "needing" the 169EUR PSU??? I started my damn post saying exactly that you do NOT yet you end yours, again, with something about needing said pricy PSU which no one ever claimed, at all??? Allo sells a $11 one for Christ's sake, who put in your head anyone is forcing these pricy supplies on anyone?Instead of trying to teach me about LPS I suggest you take more attention to what I said.
I'll repeat it with a little more detail for clarity, so please read several times before posting something irrelevant again : RPI as a platform was designed to be cheap. It was not meant to be fastest platform, nor the best in an parameter, but the cheapest. Most of it's accessories follow that logic so you can buy various "hats" that do a decent job for a small ammount of money. Saying that " you need 2x5V PSUs for best quality", and the PSU costs 169EUR, is a kind of oxymoron in my opinion as it totally misses the philosophy on which RPI was built.
Seriously dude you are too arrogant for your own good.
Arrogance— point proven? Goodbye.I'm pretty certain it wouldn't even cross your mind to talk like that if you were standing in front of me.
I know we can annoy each other but please try and keep civility in mind, this medium can make a arse out of all of us so try and give a bit of latitude to one another.
Cheers
