Tube USB Preamp


Greetings,

I seem to remember seeing a tube USB preamp for sale on the site a while back. Does anyone have any info on this? I am part of a University computer audio research lab that has interest in purchasing this.
Thx.

The Wavelength Cosecant DAC is a digital to analog converter with USB input. It can be made with a volume control which would turn it into a DAC/PRE.
Specifically, the preamp (or audio interface) needs to connect components TO the computer via a USB, or better yet, a FireWire port. Hagerman make something similar to this but the USB port is an input. I believe the same goes for the Wavelength.
Bel Canto Dac3

I don't own one and I am not a dealer but I have an acquaintance at the local audio shop and he has one. Seems to like it.
