Here's a Darling 1626 single-ended stereo amp with volume control that I built to get into the holiday spirit...yours for $500.

Here's a prototype amplifier that I built as test bed.  It uses compactron tubes, the signal section being patterned off of Thomas Mayer's 6GE5 amplifier.

Ultra Fi Basic Data Only USB Cable

Here's a data only (D+, D-, and GND)(No Vbus) custom USB cable. It is one meter in length. The fellow that ordered it never followed through. So, if your USB DAC doesn't need Vbus and you want to eliminate the nasty noise associated with running computer power through your USB cable then, this is the cable for you. I charge $350 for this cable on a custom order basis only normally but since the buyer never showed up - it is yours for $125 including shipping on the CONUS.

Chadd's been at it again.  Now he's using a pair of SuperWhamodynes with slot loaded open baffle woofers for his second TV setup.

There are so many good DACs these days...

Here's one I did with an async USB receiver based on the XMOS micro controller and the PCM5102A.  It is 32 bit and 384kHz capable.
