I wanted a multisource input/output selector box, capable of many in to many out, and didn't want to use mechanical switches. All my electronics except DAC's are tube DIY, including Bottlehead, Welborne, and many own design. I focus on Analog and Tape (5 RTR, 1 cassette, 2 TT's, 1 Tuner, 2 CD decks through 1 ADC). Although not a 'purist' approach, having an interface selector box for multiple sources is at time convenient, and cuts down on the cable swapping, etc. Also for DIY, future projects can have only a single input, saving cost and complexity.

Inspiration was the Manley Labs SKIPJACK http://www.manleylabs.com/containerpages/skipjack.html, but it was limited to a bidirectional 2IN/3OUT, and cost $900. My unit uses 2 x Darwin, completely separate, essentially 2 x 2IN/6OUT or 6IN/2Out .... you get the idea. I can even use the 2 sections together ...

I use a Par Metal case, and a clean 5V wallwart for power. Direct connection to all I/O RCA's with silver Teflon wire. All RCA's chassis isolated, and each pair has it's own separate ground connection to the Darwin board. There is no signal ground to the chassis, the 5V is grounded to chassis, and a hardwire chassis ground to the system ground. ( I do use a power conditioner that all equiptment is behind.) Use of this device has not induced and hum or signal degradation into my system that I can hear or measure, using good quality interconnects.

The Darwin is a great value and works very well. Thank you.
