A while back I had a thread about here gathering info on some active ZD5s. Well, I won;t go into the reasons, but I decided to build an amp instead and the ZD5s ampless

Case is from Modushop.biz 230x230x80 with heatsinks as sides which is very handy.
Built in USB DAC from dddac.de (thoroughly recommended!)
Alps 10k motorised log pot
Remote board from Altronics in Australia
Discrete transistor buffer as detailed on Nuuk's site

It's not the neatest, I'll agree, but the grounding scheme (despite being a bit of a mish mash) really works and it's silent as a mouse and sounds absolutely fantastic.

Amps are held on with bull clips atm as I left my AS ceramique at my other house and I'm aware I still need to deal with the safety earth. I only finished this afternoon...

I think it looks nice Valleyman. My hybrid looks a complete mess inside when it's opened, your amp looks way way better.

Unfortunately it seems I spoke too soon. The small transformer has started buzzing and is causing an audible buzz on the speakers, especially the one whose output is next to it.
I have currently only listened to it on a small test speaker so I'll see how it sounds when I have it rigged up to my newly constructed ZD5s and decide if it's worth replacing. If it doesn't interfere with my lestening I don't think I'd see the need.

The only other problem is the amp smells of electrolyte. Replaced the rail caps on BrianGTs amps with 1000uF and idiotically put the ones between the negative rails and gnd in the wrong way round leading to some reassuringly loud explosions, a lot of smoke and fluid all over the bottom of the case...

I had a reversed lytic also once in my diy history. Cleaning the pcb and removing all residues is the most difficult.

Another little pic of it all sealed up sitting atop my little mATX PC source and next to one of the MA GR10s it currently drives... soon to be replaced with ZD5s
