Still, a great way to turn a few dollars in SMD resistors into $1,000+ of audio gear.

Hopefully nobody tells them about the thermometer coded DACs or string DACs because sooner or later we will see DACs with 2^24 resistor in them.

Nah, what you need is a whiffletree DAC.  Just feel the audio purity created through the use of a purely mechanical DAC!

I remember long ago driving a R2R DAC from a 27C256 UVEPROM as a crude voice playback method. Never knew it was sooo fancy!  ;D

Love how they called it a "Professional designed o-ring transformer" in that thing.  ::)

use wet string if its an AES signal

Just remember to never run your o-ring transformers at temperatures below 53 °F (12 °C), lest it cause o-ring erosion and they let all the electrons out.
