Wow! the WOOAUDIO 3 - Page 2

I wonder if he could use a 6cg7 for the driver tubes instead of the 6922's. I think the 6cg7 is a lot better sounding tube. The 6cg7 is more rugged too. The size of the tubes and pinout is very similar.

I wanted to do a Pimeta vs WooAudio 1 comparison, but the Pimeta didn't stay in my hands very long after acquiring the WooAudio

I should be able to build a ppa in about two weeks time, and can do a comparison between it and the WA1, if there is interest. Keep in mind that the ppa would be the my first attempt at building an amp, but I hope for the best!

It sure is a sweet looking amp. Looks very, well built.

Much relieved... I was hoping that you guys were right about the preproduction theorys. Mr. Woo better post that additional photo to the website so no one else has the same question. I would love to be the one to audition the woo 3... maybe I can make up for my cry of concern by giving it a fair shake against my other amps (RKV, BADA PH1, and hopefully soon a MG-Head MKIII)

kind of reminds me of something ray would come out with...as far as the looks.



all black tube amp= pissed!


hey woo send me this one too....lol hahahahaha

anyone getting it for the special introductory price of $500 + shipping? I would like to know how it sounds compared to the PPX3 or PPX3-6SN7 since it is roughly the same price of those.

Or maybe that's just a built in xfeed

dang, only $499? I wanna upgrade

Any idea how this would compete with the PPX3, theoretically? I'll order and review it if it can match or come close.

The Eddie Current hd 300 is a design a lot like this. But the hd 300 uses a 6sn7 driver tube vs the 6922's in this amp along with the same 6as7/6080 output tube. The 6sn7 is a much better sounding tube as well as being much more rugged. Earlier in this thread I thought outloud about using a 6cg7 driver tube in the Woo(very close in size) which is another better sounding tube thats again far more rugged and reliable. I have used 6922's in preamps for years and always had trouble with section matcing and reliability. I also know the 6922's I have tried sounded either to hard and bright or to dulled. To get a good 6922 or 6dj8 you have to pay $$$ and they are hard to find. Still my big gripe is that tube sections match poorly and the tube never holds up very well, even the good Amperex(real nos) ones I bought from Upscale Audio. I have not found even the best sounding 6922/6dj8's to be anything special.

Now assuming the hd 300 might be a little better than the Woo because of a better basic tube compliment(I have not heard the Woo), I know I like the normal 6cg7 based ppx3 a little better than the hd 300. So, IMO I dont think the Woo will measure up to the ppx3. I have a special ppx3-6sn7 on order that will also allow me to use the big 6080 output tube x2 on the outputs. This amp will drive k1000's too. I do like the 6as7/6080 output tube. I also think the 6080 is a much better tube than the 6as7's from what I have heard from the hd 300 so far. Nothing is definitive here as I have not heard the Woo. But I dont trust the 6922 tube, so I have my doubts about the sound and using two 6922's looks like twice the trouble.

Remember this is conjecture, but I have owned both the ppx3, had the new ppx3 for extended audition and I own the hd 300. The question asked THEORETICALLY how would this amp would compete with the ppx3. This is an honest answer not an attack on the Woo.

Earl,

I don't know. I like the Singlepower amps as you do, but when I had the WooAudio 1 with me it sounded pretty good. I wish I had the opportunity to hear the new WooAudio 3 and compare the two, though what I'd really be interested in is how it functions as a preamplifier.

I dont know either I havent heard the Woo, but long term the 6922 tube is trouble IMO. The Woo likely does sound good, thats a tried and true circuit. But I am VERY familiar with the two other amps and the 6922 tube; and as long as the Woo uses the 6922 I know I wouldnt buy one. I have the $110 Chinese amp and I am going to have it modded to use a 6CG7 or use the 6NIP. I am very biased about the 6922 tube. I dont like when the channels arent matched and I have never had a 6922/6dj8 that maintained a good match between channels for long. Thats bad enough with a preamp but with headphones its even more annoying. 6922's can be noisy too.

Doesn't the SHA-1, the perennial favorite amp for the hp-1000s, use 6922s for its drivers?

Yes it does. Despite this amp being a favorite with the grados it is known for its upper midrange glare when used as a preamp. The brightness may be what makes it mate well with the hp-1000 which has treble on the dark side to me. The glare may be related to the 6922 tube as well. The JAN philips 6922, for example, have a bright, peaky character when I used them in my preamps. This 6922 tube is very easy to design around because it has a low output impedence. The specs on the tube seem ideal but the results much less so in the circuits I have actually used them in.
