I finished up my "old" Buffalo a couple of weeks ago. It has two coax inputs and two toslink inputs via the mux module. In addition it has a i2s input that takes DSD or PCM from a modded Denon DVD player. I only got DSD running at the moment though. It also has the volumite for volume control when I run headphones straight from the balanced IVY output. It also has a custom pcb for the pcb toroids as well as a small board for the input selection leds. Almost everything is twisted par, except the power on circuit which is from amb.

Wos! most professional and good looking job I've seen so far. Congratulations! One question: Is the switch a momentary contact switch? How does it work?

Thanks :)

The power switch is momentary and it needs a separate transformer that is always on and a circuit for switching the relay that controls the main power. Its made by www.amb.org. It can do thermal control as well if something overheats, but I left that part out because I didn't see the need in a DAC. It powers the LED in the switch as well, so very easy to setup. A little on the expensive side for just a power switch though, but it looks so cool :d/

That's fantastic and has all the features that I'm dreaming of! If you don't mind, could you please tell me how much everything together cost you? Thanks!

One suggestion. On the IVY remove C1-C4 and add C13-16 using 1nf in those spots. I think you will like that change. :)

I just got the AMB labs E24 and I had the little trafo board made to match. (I ordered 30 of them since AMB stopped selling them!) ... where did you get the trafo's and the large PCB board to mount them on?

The big trafos are made by Toroid and I got them locally here in Sweden at www.elfa.se. Next time I will get Amveco pcb toroids instead since they are dual primary and a little more standard. The board is designed by myself and made by Olimex.
