That woven fiberglass/copper braid looks like great stuff but pricey at $32/meter. I guess you don't need much of it for a small preamp or HPA box. Thanks for the link.

I wonder if solder wick braid could be used for smaller cables. Sometimes, stripping off braid from used RG58 coax or household cable coax leftover bits can work too.

In the meantime, I'm pretty happy with the finish on this build.
this looks great, the sleeves are a nice touch - looks like you took a page out of the PC building book :P

Thanks buzz.

True, it does look like the PSU leads inside my PC! Must've been where the inspiration came from

I'll play around with it again at some point - I have an additional input to wire in when I decide what to put in - and might change the PVC out for the proper shielding sleeves (I've got an old stash of it somewhere).

I'm currently running an rPi with Volumio through an original hifiberry dac into some Audio-Technika ATH-M50x and it sounds pretty nice to me. Definitely worth the headache of soldering SMD!
The ever growing project list.. :NAP140 Clone, NAD 3020i & 3225PE, JLH1969, TDA2050, Fender 5F2A Princeton, NE5532 Pre, SHPA, B1 Korg. : VSQC Phunk Style, Retro 50W, Filmosound 601. : Apex AX-14, TGM-10, TDA7265, LM4780 (Last in line)...maybe
