I'm gradually re-reading the earlier pages and trying to get all caught up to the present. Over the last three or so years I can't remember how much of this I read!

So here's my other dumb question: Peter based his implementation on the Shigaclone work which had been done around the same time, but of course did his additional magic and wound up with something that he felt bettered his many purpose-built high end transports (one of which I own myself and some f which I'd heard in my own system). With the evolution of this current project (integrated PCB, SMD devices etc), does anyone know what we'll get (sonically) relative to what has been described from these earlier, more discrete build efforts? I suspect I'll be pointed to a page that I have gotten to yet , but I'd appreciate help in getting caught up.

We will get a transport which should theoretically better the original Sanyo, by virtue of its dedicated regulators, and also unnecessary parts being removed. The operative word being "theoretically" - no one can say for sure how it will sound until we build at least one prototype because we will be using completely different components...

Yes, that makes sense. I wonder if it makes sense for one prototype to be built once all the parts are in. Run some listening tests on it, beat it up a bit, see how it does. If there is yet no prototype it may be udeful to see if there are any PCB or part problems.

I wonder if we could entice Pater to listen to one of these against his own creation and his retail transports?

BTW uncle_leon, do you plan to do any of you custom capacitor magic on this PCB version?

I want to have board tested and working with all modifications in place before the start of group buy.
I'll do my best to honor all requests, so this should be your last concern.

Thanks BMW850.

I really have to get through this whole thread!

Indeed, I do

Actually, I was looking at the parts list, and realised that we don't have a suitable replacement for the "C906" cap (that unassuming electrolytic which was responsible for the Shigaclone "magic").
Some of you may remember I was doing extensive capacitor listening tests a while back, and found that very few capacitors sounded satisfactorily in this position, and the ones that did were rather expensive (namely Duelund Alexander and V-Cap). What I'm saying is, our transport WILL sound worse than the original in some aspects, if we just use a generic cap here.

With that in mind, I thought about my hand-made capacitors. I have a lower-cost design (which actually beats Duelund Alexander), but I realise that is still too expensive for most people. So I thought, if there was interest, I could re-design it - cut a few corners and bring the price down, while keeping the sound quality good. With my cap the sound would be significantly better than with the original, "magic" C906. I was thinking long and hard, and I really don't think I can make them any cheaper than 15+postage, assuming I was making at least ten. Would anyone be interested?...

Count me in for two of them uncle_leon!

Thanks and regards

What are the dimensions of the redesigned cap? I might be interested if its a manageable size.
