Believe me, I was skeptical, too. But look at this:nige2000 wrote:mark
did you ever test the passive seasonic atx supplies?
how does the pico + linear compare to the leadex?
im a little skeptical :)
the problem with the dac-up is that it still sources the +5v from the motherboard, its a sort of half way sort of thing and still requires all the further modding :(
fractal make lovely cases :)
were a bit of a divided bunch here
theres those who are really into ca and want the best and those that cant get far enough away from it
there is a couple trying it out low level style but not many
think the bbb and tp botic (properly implemented) will clean up the bottom half of the ca market (maybe more)mostly because of sq but also the simplicity and foot print it can have

Seriously, though, for less than half the price of a JCAT card, this combo is a knockout.
Sorry to harp on about it, but we were the first people to shout about the Pico PSU + Linear combo as a cut-price alternative to our multi-rail linear - back in 2009. I was wedded to the thing, but only out of desperation: nothing else let us use a linear for AC-DC quite so inexpensively and simply. It's a shame, because the HDPlex version is a nice step forward, but then - out of the blue - this!
It's so much lower noise than the PicoPSU it's not even funny. I can't begin to tell you how gratifying it is to have practically infinite headroom available on three ultra-clean taps for 3.3V, 5V and 12V: shoot one into USB, bypass the PCIe bus with an injector ribbon - no problem. Obviously you don't want to be passing it off-board recklessly because the board injects plenty of crap back into it - but what a novelty! A PSU that need protecting from the board, not vice versa! I like it.
It works great with Core Audio filtration, and like any PC it benefits from mains isolation, so I'm certainly not suggesting the basic £600 T1 is the last word. Far from it. But it's definitely a new platform - all shiny and Haswell - to build for 2014 and beyond. More memory bandwidth and full speed PCIe for USB cards - ready to rock and roll. We're still ironing out the latency bugs, but I think we'll a few OS images in circulation soon.
The dual 25MHz clocks on that board are nice and accessible, too - through-hole jobs . . .
I'm pretty strongly anti- boards bigger than Mini ITX. Although the spacing of the board is sometimes a bonus, they suck more power and generate more RF. It gets a bit troublesome to be developing more than one board, so we'll be tweaking the heck out of this one unless we hit an insuperable problem running software like Server or run into glitches with driver clashes down the line. No reason not to use this board for the JCAT, SoTM, Adnaco, et al, even though the fancy bus is then wasted. It's still an ideal board for a single-card build: only £65.
