I have used the Waveterminal for almost two years now. It a a great device but I am sure one f its short comings is that it draws its power from the PC via the USB cable. I have spent a lot of time listening to it as a DAC and it is phenomenally good sounding given its price. I am awaiting one of Empirical Audio's new wirless USB offramps. You can find info at their site.
any words of wisdom for usb noise problems?
i thought usb connections would be trouble-free after placing waveterminal u24 between my desktop pc and the dac in my panasonic reciever (office system). itunes runs dead quiet there. i am trying to implement a pc feed into my levinson preamp in main system. when the usb cable makes contact between my laptop pc and the u24 running into the preamp i get substantial noise, which is substantially worse when a usb hard drive is also attached.i googled "usb noise" and saw references to some midi users' and photo printer issues and some filter products (argh!- hope to avoid this step). also mention of computer screens as possible culprits any suggestions or similar experiences?
