Sonicweld or M2Tech hiFace usb to spdif converter


I'm diving into the PC audio arena and need a good interface between my PC and Esoteric D-03 DAC. I've looked at these and the Off Ramp by Emphiracle Audio.

Any suggestions on these?

I love my M2Tch Hiface. Is the Sonic weld 10 times better? I don't know but it cost almost 10 times as much.
Check out the latest review in enjoythemusic for a comparison between Evo, Halide Bridge & Jkenny modified Hiface

I have owned the HiFace and the EVO and now have the Sonicweld Diverter HR on the way. I can say based on my own experience that the CA review was garbage. Without going into detail, note who advertises on that site, Wavelength and Ayre (which licenses Wavelengths USB microcode)... See a picture forming... The HiFace used with my Mac mini and super Bidat and MSB PowerDac was superb! When the EVO was substituted for the HiFace it got even better. I read that review (CA) and scoffed at the findings....pure hogwash!
Use M2Tech EVO to isolate Switching Mode Power Supply noise
from PC to Analog Power Supply of Tube Rectified/ Tube
Analog output Stage DAC. Tubes are highly suseptible to
PC SMPS. EVO does this in spades, as well as convert USB to AES/EBU Digital. Difficult to install EVO Drivers.
Blindjim-been concidering using J River Media Center. I
currently use Windows 7 OS with EVO. You said you had problems using the new M2Tech Drivers, especially utilizing
J River with Wasapi? Anyone else have similar problems with
EVO as well as hiface under same conditions?
