Does anyone have experience using the Wadia for digitalizing their vinyl? I've used the Project Phono amp with the USB output for this purpose, and I find it a pretty frustrating piece of equipment. Some recordings fare well but more often than not there is a loud hiss which doesn't actually seem to be reproduced through the rest of the system as the record is playing. The Wadia says something about having to be used with a CD-Burner. Is this really the case, or can files be burned to a hard drive?
