I'll give it a go one day in the new year, I have all the motivation of a sloath on mogodon wrt actually heating up the soldering iron at the moment, it's sounding pretty damn peachy!

Great thread.

Hi,
this is my QC24 after having received a selection of Epcos' and Rubycon's finest. Now the bass has returned, but the impact on the sound of the internal phono stage was much bigger than expected.
The mains cable is connected because this is a test run to see if any caps would explode due to reversed polarity. Otherwise, this would be a bad idea.

Hi,
A PSU for a Nac72 using ALWSRs, Cerafines and LesW transformers:
More recently, a split rail supply for my brothers Exposure VII pre-amp, this time using Teddyd ALWSRs, Cerafines, LesWs transformers and incorporating a leaf-spring suspended regulator plate. All shoe-horned into a Naim sleeve:
And heres one channel of a recently completed Hypex UcD700 based power amp. This is for Andrew, starter of the Hypex thread, way back when. I guess I'm not the worlds fastest diy-er...

Thanks for the comments, guys

I haven't done the comparison myself, but I believe my friend, who this psu was built for, has done the comparison and he certainly seems pleased with it. I think one of the key things to getting the best out of the ALWSRs is LesW's brilliant transformers. I didn't try that many different caps but get the feeling that they may be less important(?). However, since this psu was built (over two years ago), there has been lots of work by the folks on this forum and I'd particularly recommend Teddy Pardo's VBE mod for this regulator as, imo, it provides another big-up in performance.
The idea of springing the regs started out as a bit of fun because there seemed plenty of room in the case, though it ended up becoming a bit of a pain and I would have ditched it if I wasn't so stubborn. No idea if it actually makes any difference!
By all accounts, my earlier stuff was way worse than Blue Peter! The later certainly had a big influence on me - very difficult to walk around B&Q, Lakeland Plastics, etc without thinking hmmm, that could be a housing for a phono-stage... The other big influence was that (80's?) Naim leaflet/poster of the insides of a 250 - I've always strived to try and be as neat ever since. The downside is that it then takes me ages to actually do anything.
There's more of my meddlings on a website I've put together at http://www.nodecorporation.co.uk/ hopefully diy-ers might find it of interest. It is a bit anoraky, though...

I'm certain that the Fcap built by geesixty is quite a bit better than a Hicap. I don't know whether the difference is mostly down to transformers, to the superregs or the overall standards of construction. But it's certainly a damned fine power supply that sounded quite a bit better than an admittedly old Hicap in a fairly modest system like mine (currently old 250 plus 72) and I'd recommend it.
If you want details of how its better than a Hicap - well in everything really. Clarity, timing, sounding like music, lack of hash between notes, drummier drums etc etc - just no comparison.

And you've succeeded judging by the projects on your website.
Superb construction and attention to detail.
Paul.
