I've been playing around with smps lately and am floored by the difference they make on my chip amp and dac. I saw the inside shots of the KingRex with a small torodial and it looked interesting. In the 6moons review they rave about how the amp sounds with the ps. Natually, since we all know how important the ps is.
Anyone have a schematic for something like the 12VDC KingRex?

Just finished a long search and reading. A hot topic. Since you know about them is there any conclusion on a schematic or a board or kit?
I found this kit. http://www.chipamp.com/supply.shtml
Any experience with it?

How do you compare it +/- to SMPS?
I haven't compared them directly in my present main system as the SMPS causes some weird noises and I am yet to find the problem. In my second system, they sound quite similar, ie both as good as I have heard with the GC. Lots of power without sacrificing the mid-range/top-end strengths.
That looks a lot beefier than the one I got from ApexJr.

I read the one you're using is hard to get in the US. Is there a comparable model to that you know is available here?

I don't know if it is possible to say that one SMPS is better sounding with a GC than another. Probably the only way to find out is try them. I only have experience with the Skynet 8080 modules.
In the early days of this chip amp forum, some people even reported good results with PC PSU's.

I've been meaning to play around with some sort of filter on the output of the SMPS but not got around to it yet. I have a feeling it may be one of those 'suck it and see' jobs where the best option is empirically based!
I'm afraid the answer you your second question is the same, ie try it if it doesn't cost too much!

Nuuk. I've been playing around with dampening the SMPS. Just a bit of blue tack on the top of the caps made a HUGE difference. I just did it as a lark and was not in any way prepared for the results. Since then I dampened all the caps and transformers. The sound stage EXPLODED.
Give it a try. Cost a few pennies..
