I might give a go tot he power injector. I might see if resoldering the SMDs changes anything. Checked the voltages on the 1117 regulators and they seem tpbe stable and holding on. interestingly - when i was testing outside the box, it was behaving better than in the box. so it feels like a funny USB issue. elswhere there had been words that some USB DACs relying on WIN7 + for drivers may be affected by DRM checks, but alas - those things I can not verify. I might try and get just the board from HIFIDY and see where I get. All the Software stuff ( drivers, chispet removal , USB controls reset etc) already done, still same symptos. So I am pretty convinced it may abe aborderline component of sorts, so willkeep on digging as time permits.
Looking at the win 7 comments - I ahve a couple of Macs at home, so will see if that changes things some ATM I am using Logitech Xfi HD - pretty good for REW measurements ( which is why I bought it in the first place) , but does not sound as good. I"ll keep you posted. have been a long time lurker, hopefully I can do a little more than that and return some of the goodness.

Please keep us informed. USB can be a real P.I.T.A.

Up until recently I would have agrred with you. However, I've found 7 to be a huge improvement on XP, still familiar, far more logical and much slicker. 8.1 takes some getting to know, a few freindly tweaks and some patience and it really isn't as awful as peeps say. I even find going back to 7 a little "quaint" at times! DITTO. Perhaps Mike is suggesting that XP didn't have such weird USB problems ?
Yes, I was suggesting that Alex

Ok, So quick update - I - resoldered every joint - the lead free solder is not the best thing to work with . When connecting outside of the case, the DAC gets recognised and works. the moment it is assembled it stops being recognised. so it does look like some component is marginal and when grounded causesa problem. I thought the virtual ground from the 1875 was causing an issue - but it does not seem so. I am about to try to get the board and components only - this is available as a kit on hifdiy.net so it will take less time to assemble than to diagnose, especially since i don;t have the original diagrams and any testing/ measurements points
Thank you all ,
Vlad

Hi guys, I just got myself the Aune X1 Pro today and am having a lot of fun with it (especially when I got it at a good price, first-hand! May I know if any of these mods (PSU, opamp swapping) still apply?
Thanks!
