Wow! the WOOAUDIO 3 - Page 2

post #16 of 54
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)

That's a good looking amp... what kind of tube is that big one in the center?
the big one is 6080/6as7 power tube.

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.

edit: I can hear the crosstalk only when if I adjust the balance to one channel, or only connect one channel.

Oh, and the transformer box does indeed house a transformer.
Or maybe that's just a built in xfeed

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.
