these showed up at diyinhk
there a 384khz version of the 768khz we've been so pleased with using the same xmos chip
http://www.diyinhk.com/shop/audio-kits/ ... f-pcb.html
as i never use anything above 192khz having a 768khz is like using a formula one car to get to the corner shop
i got two for 100$ + shipping

OK these arrived and sound like a good step up from the last gen 6 core
I'm will have to test against the 768khz model guess it will be close

yes i wasn't expecting much difference either
seem quieter/ blacker background more resolution/ air/timbre /separation
just that bit of finesse that makes the difference

Looks like wiring = input is xD and output is equivalent xQ...

yea but i just glanced at it and hooked all up along pin numbers as 1q/1d/2q/2d/3q/3d thinking it was a pattern
but its 1q/1d/2d/2q/3q/3d
and that had me checking stuff for half hour.... doh....

I have installed the potato flipflop. I gave in only because they are so cheap and easy to source here in the states. Had some issues at first, not sure what, but after some rewiring, got things working. I'll need a little time to articulate the difference (and let the solder and chip cool). As of right now, the pacing/timing seems ever so slightly slower. Presentation is more relaxed, refined, articulate. Yes, I think lower noise. Makes my setup sound expensive. Potato need to advertise this chip next to a bottle of the good stuff (insert your fave).

This is as good as any point to pause on this hobby for the time being - priorities have shifted in recent days. Many thanks Nige. The potato is the icing on the cake. The diyaudio soekris crowd don't know what they're missing!

i think acko uses the potato chips too, maybe some others but not many do, rather save a couple of bucks

we all need a break from diy now and again,
thank you for trying the mods and contributing, was great to get second opinion on stuff,
unfortunately too many just talk but no try :( (granted not too shabby here)

have a good break and dont forget to come back

Its taken a few weeks from Japan but finally got 6 of these Potato Reclockers today.

These things are tiny, never expected that from the picture!!!

Might try and see if I can solder direct to the legs first on one as I forgot about boards for them and even if I had boards I would never be able to get them soldered onto the board.
Will be a test for a steady hand.
