Just picked this up from the Post Office today and OH MY LORD!! I plugged this sucker in as soon as I got home and noticed the difference RIGHT AWAY! 0 Buzzing and the sound just comes out crystal clear from my monitors now.
Thank you soo much for this beautiful product! Already recommended it to my friends.
I received the isolator today. Without isolator I hear white noise and a glitch every second from my amplifier when the volume is more than 25 % open. Now with USB isolator my amplifier is dead silent even with volume 75 % open.
It is transparent and works out of the box up to 24 bit 96 kHz without any specific drivers. I use it between my Sony Vaio laptop and my Musical Fidelity V90 DAC. My OS is Linux Mint Xfce 17.2 with Audacious as my audio player. As my laptop's battery is dead I always use it with 220 V power adapter. Because of this I had a ground loop between my laptop and DAC. I am listening 24/96 flac files for 2 hours now and the isolator works like a charm :-)
Thanks HifimeDIY! I also would love to test your new ESS Sabre DAC but I will wait for a version with stereo RCA output connectors...
Does not work on Focusrite audio cards. Looks like 200mA is not enough to power up any card with mic ins and headphone preamps via USB. Hifimediy reply: Yes it generally doesn't work with sound cards that has mic inputs (phantom power) etc. We'll add a note about saying that Focusrite is not supported. You can always ask us for an opinion on if it works with your device before ordering.
I have a Raspberry Pi B Version 2 and am able to get a HiFimeDIY Sabre U2 Asynchronous USB DAC working with it. The only mod is to prioritise USB audio over HDMI and analogue.
I also obtained the HiFimeDIY USB Isolator, but when this is installed inline, the RPi is unable to identify the DAC at boot up. This is not a show stopper, as the DAC is working fine and I am not experiencing any white noise with it. This DAC is only designed to go to 96khz, and I am satisfied with that.
If you have a dying motherboard and can literally hear the hiss/fuzz difference between different USB ports, then this is for you
Does as advertised
