No I haven't but knew of its existence.
I like the idea of a modular design.
The power supply thing is and 'short signal path you don't need cables' thing is a bit of nonsense really.
All the sources and speakers/headphones still need to be connected. The only interconnects you 'spare' are between DAC and pre-amp/power amp.
The connections are still made with copper.
An integrated DAC/pre-amp/headphone amp has the same 'advantages'
The power supply differs from others but the 'sonic benefits' are marketting talk.
The only thing it does better is problems with common mode currents (especially with SMPS).
What the power supply does is charge 8 caps (he claims directly using no rectifiers) while 10 other caps are feeding the circuits.
When the voltage drops below a certain voltage the charging circuit is disconnected and the emptied 8 caps (2 are always connected) are disconnected while the 'emptied' caps are connected to the charging circuit the filled ones supply the power.
This switches around and around.
How he manages to avoid 'jumps' in the power supply voltage when switching I don't know but reckon the 'switching' is done by slowly connecting the 2 banks via MOSFETS that turn on 'slowly'.
His claim that no rectifiers are used is nonsense as AC cannot charge a DC capacitor/battery.
Diodes are obligated.
He doesn't use transformers or SMPS so charges directly from mains.
What he did to allow for 110V/230V is a bit vague.
IF those caps are charged directly from mains one would better hope the circuit that disconnects the mains NEVER breaks down.
Should it 'hang' for an obscure reason the amp could be connected DIRECTLY to mains !
When 3 prong sockets are used this doesn't have to be dangerous though.
Another 'disadvantage' may be that you will always have to use Vincents designs.
No way you could want another DAC, another type of power amp in case you want moar powerrr etc.
Picking your own components gives you more freedom (IF you need it)
His designs will probably be 'transparant' enough and he thought of a tube buffer as well.

Then I guess you have heard of it! What a great explanation, I was not going to buy, of course, but interested in what someone with your knowledge, would explain it. I like the idea of plug in modules, but it does limit you to only one persons system. Thank you for the explanation. All the best.
