I'm selling a couple of items that I used to link my Apple Mac USB music server to my M gear.Halide Design Bridge - USB Async to S/PDIF (RCA) - £235
Basically ultra low jitter digital audio signal straight from your computer USB. 24 bit resolution at sampling rates up to 96 kHz, and works with virtually any file type and player. I've been using to link Apple Mac and Amarra to my M gear. Great sound with CD or HD (up to 24/96 kHz) sample rate files. More Info
.Aqvox USB Low Noise Linear Power Supply A - £40
Basically replaces the USB power supply from a computer with a linear power supply that's regulated and stabilised,
preventing power noise related issues. Can be used with the Halide Bridge. More Info
Postage to be agreed.
