Hi Fred,
Have you got any experience in this, does the different dielectric in fact change the way people perceive the sound. If you have any kind of test / measurement / proof / calc that back your claim – by all means present it, and convince the rest of the world that the practice they have been using for the last – I don’t know how long – is wrong. Tell us what we need to do differently, single sided PCBs with long component leads seems to be a very poor alternative to SMD components with short signal traces, small loops on the PCB and more often than not a better low noise design because the currents in resistors have to be smaller in order to make the design workable from a thermal point of view.
Of cause you still have to think about you layout when making multilayer PCBs, but you can incorporate a very effective ground philosophy and separate the different planes nicely – I have seen it done
Thanks

I have made a survey about the results and the fact is that noone has built a working regulator, meaning that noone has finsished the building. I'll hope that someone really connect the regulator in a electrical circuits some day.
With this I also want to point out that don't buy any pcb's for my SMD Gainclone if you aren't dedicated. I don't mind that I can order at least 100 boards but it's also a waste of money if the boards are unused. The difference between the regulator and the Gainclone is the SMD elctrolytic caps which the regulator has. Those are a bit hard to solder if you don't know the trick since the pads are under the cap. The Gainlcone has no such caps and the pcb is quite easy to solder.

Just wondering, when you talk about Audiocom, do you mean the very tiny Sulzer regulator with all SMD parts or do you mean the one with holemounted parts where those parts are very tight fitted?

Audiocom Sulzer regulator has very little decoupling so you can wonder how good it can take nasty loads. I have one Audiocom regulator but I haven't tested it with difficult loads. It may be good, who knows?
