i did listen to the stock, unbroken in woo 2 they had there and while it lacked the bass ext. and refinement of my woo 2 the sound was going in the same directions.

i forgot to mention that jack wu mentioned that the upcoming balanced amp will be based on the woo 2 and called either the woo 22 or 2200, something along that naming scheme.

If you went with black, count 2 more weeks.

WA2 received !!! damn this amp is a monster of steel ! It's crazy heavy and built like a tank... and really better looking in real than on pictures.
I'll put some in the forthcoming days.
I've checked the component and noticed a slight difference with the JayG model. Instead of having 2 BG coupling caps, I have 4 of these... don't know why.
Sounds pretty good for now even if bass is tight and congested and the 1-3 khz range sounds agressive. Maybe because I'm using a k701 (the amp really have enough power to drive it !)
Transparency is simply unbelievable. I can hear background noise on records I've never noticed before. And it's not due to the amp. It is dead silent up to 75% volume.
More feedback to come after more listening sessions.

Good stuff! Congrats and enjoy it. Perhaps the difference is due to the PSU upgrade implemented a couple months ago?

I'm eyeing a pair of 6N5S power tubes (military version of the 6H13C I believe) for possible rolling.

In my understanding, it's because the caps are different.
I have 4 100v 220uf instead of 2 160V 470uf as in the JayG version.
I guess it's pretty much equivalent but I'm far from being an electronic specialist...

If anyone has tested the WA2, WA5, and the Zana Deux, which one of these amps have the blackest, most silent background, even a large volume levels?

I guess it depends a lot on the tubes people use with their amp but a comparison with stock tube would indeed be interesting !

My WA6 is absolutely black at max volume, if that helps at all.

Ok, I should withdraw my comment about background noise on my brand new WA2... don't know what was causing it but it's now totally black up to max.
On the other side the bump at 1-3 khz is still present and make stuff like pixies really sound bad. Hard to describe but these frequencies are just piercing, sounding well over anything else. Not really luscious and organic as I would have expected !
Too bad because its sounds so natural on other genre, say Calexico, or even on electro where the k701 is suprising !
I just hope the burn-in will solve these little concerns.. or maybe other tubes... or something more fun than my K701 (grado or sen ?)...

Here are some pics in the silver version. Really splendid.

Great pics! There isn't anything about the WA2 that isn't beautiful. I've had mine for over a month now, and it still amazes me every time I listen to it.

I suspect you know this, but there was a thread a while back (in the last two or three months) about that bump. IIRK the sense was that it was a particular 6DJ8 / 6922.

Apparently this is an inherent problem with the JAN Philips 6922/6DJ8. I believe the recommendation I have heard to remove the 1-3khz bump is to use another type of tube, for example the JAN Sylvania 6DJ8.

I should be able to tell whether it's the answer or not as I have some Bugle boy 6DJ8 Holland on their way.
