D200 Mod 2.0.1

I know it's hard to not think of meassuring   .

What I want to say is that a Pin Connection and a Direct Wired Connection might meassure nearly the same but only on the meassuring you are used to. You can only meassure values you know of...but I can imagine that 'science' does not have the whole picture yet. I don't have either. But I've got some very good ears...and I trust them 

If your mod is easily audible, id say there's zero chance that the difference can't be measured, and to some precision. No doubt using the same kit Devialet design and test these boards with (else they wouldn't exist or improve since Devialet say they measure only). With the right kit we can measure the weakest analogue signals at a sub atomic level, so I don't think audio bands are untapped scientifically.

Ok so the kit isn't cheap or readily available, and you'd also need a lab, and knowledge and experience - to both take the measurements and interpret the results - but if there's a difference I'm sure some numbers could be put on it.

If it were a huge improvement, I'd actually be tempted, but the ex-scientist in me sort of wants to know what's changed too.

More disappointing is Devialet. If soldering a few wires made it sound a lot better, it seems pretty lazy not to do it on kit that costs as much as it does. Well, at least not doing it because it makes assembly easier is just silly. This isn't mass market electronics.

I'd be worried about warranty. Maybe we could petition Devialet to do a second upgrade scheme, where for £50 they'll take our amps back, solder these connections, and send them back to us under warranty?! Bung in the streamer board at the same time. If we had concrete measurements we might have a chance to persuade them!

GUI, I think you mentioned you might have a modded one in the UK to listen to at some point? Maybe you'll mod a Pro too?
