Not really a "STROKE OF GENIUS" but very useful nonetheless.
Very useful and cheap way (approx £3) of isolating the noisy usb supply from your PC and replacing it with your own clean linear or battery supply

I use an Ankaka battery with my BM2 and power my Hiface 2 usb-spdif via this power injector from the clean 5v usb from the Ankaka. But any clean 5v supply
can be used (linear or battery) with a suitable 2.1mm power cable.
Had to get mine from Germany and it cost me 4 times as much in postage,but if you wan't one have a mooch around as they were for sale on Amazon although currently out of stock
Soundwise my system seems to benefit in the retrival of tiny details which clean power brings and as an aside i,ve just done Stans new BM2 firmware mod which is a significant step up in sq and i feel deserves a mention.WELL DONE SIR!
