After looking at all these builds I dont even want to post my iteration of the Digital Design preamp :rolleyes:
Ofcourse it could add to some good humour :)
Please feel free to post, Kannan:)

Even my PAM 12 pre build is fairly messy as I have re-utilised my old DCB1 cabinet.

I'm not sure how magma plans to use the second output but as far as I know he doesn't use a sub. The two outputs are simply shorted to each other without any crossover - they're just paralleled outputs.

At home I could only try one output at a time so couldn't test for interference or ground issue.

The blue/violet coloured cable is a Helusound AES DMX cable (I think this DMX cable is meant for wiring up AES/EBU digital audio patch panels with XLR sockets). Yes, it's a digital cable of 110 Ohms characteristic impedance, and may seem unorthodox in this application, but I have tried numerous cables (various balanced analog cables, silver-plated copper, tinned copper, multi stranded copper, solid core copper including CAT 5/6, high purity solid core silver, etc as analog internal signal cabling in line level preamps, phono preamps and power amps and this Helusound consistently sounds best to my ears.
Where can I buy Helusound cable?
