I got both.

I don't think 5U4GB is really that much better than Halcron. But, 5U4G ST is really great.. Big improvements from Halcron.

My current setup is:

Tung Sol 5U4G ST along with Tung Sol 6DE7.

Well guys I received my WA6SE a couple days ago and have to say I am already impressed with the sound. I hooked it up to start burn-in and didn't want to listen until it was at its best. Well I couldn't help myself and listened about 15 minutes in and boy did it sound awesome! If this thing only gets better with burn-in then the sky is the limit!

As with everything else concerning this forum, of course I have gone hog wild with tubes. I think I already have more rectifiers than any human actually needs. It will be fun listening for the differences. I am saving the Sophia and Full Music 274b/n+ for the future. The EML 274b will also be added some time in January when JAC has them back in stock.

gotta warn you, the full music 274b/n+ has a current draw of 4 amperes...
this may fry your wa6SE power transformer. the 274b/n draws less than 3A.
the 274b/n+ is the extra tall slender version; keep away from this.

takezo

Thanks for the warning! Its a good thing JAC didn't have it in stock! I just checked my invoice and we substituted the 274B/n. I did also add the 274A/n/+ though. I will have to read up on the specs for that one. I read some material about the original Western Electric versions and thought the B was basically a newer version of the A. There is clearly much to learn here!

At least i had a little beginners luck in not getting the 274B/n/+ then.

Another question, is there a owners manual for the wa6SE as I didn't get one. Specifically what the ratings are and what ranges I need to stay within?

Gratz on the new amp, Derek!

If you send me a PM with your email address, I will send you the pdf owner's manual. Unfortunately, it doesn't help much with tubes. The best thing to do is search on "wa6 tubes" for posts by takezo. He has published a complete list of compatible tubes somewhere, but I can't remember what thread it was in atm.

is woo audio wa6 better than dv337?
post #232 of 508
As a newbie to the site and after only 1 meet (the recent one in Harrison, NY), I have fallen hard for the Woo amps. I've always wanted an SET amp but knew with full range loudspeakers and liking full symphonic and organ music that a SET is limited. Using such an amp with Headphones is another matter entirely. I am seriously leaning to the wa6se, only because you have a tough time adding real estate. As much as I would like to be perfectly happy with the wa6 (and it does sound great), I would really feel crappy if I would have to sell it just to buy the SE later on. Since you can't upgrade the wa6 by buying the PSU later on you are stuck with a tough decision at the beginning. To say that I am conflicted is an understatement.

That said I am enjoying the site, am quite surprised not being a headphone person in the past and dedicated to floor standing loudspeakers. I plan on getting a Predator for my laptop and portable listening, but a full can amp is definitely in my future. Any other suggestions from the more experienced members is definitely welcome.

Welcome to Head-Fi, and sorry for your wallet.

My recommendation is go for the home headphone amp first, and don't try to make do. Leave the portable stuff for later unless that is your only avenue to listen.

Between the WA6 and WA6SE, go for the gusto!

Once again, takezo was right about tubes. I finally found a RCA 5V4G (1948 NOS) at a good price, and got it yesterday. It is luscious! The bass is very sold indeed. I was very pleased with this tube so far... we'll see if there is any noticeable change during burn-in.

Hi, after many comparisons, i can say:

I prefer all 6ew7 tubes over my RCA 6de7.
I have a pair of GE 6ew7 (with +300h) and a pair of SYLVANIA 6ew7 (with +200h ). And I prefer clearly the GE 6ew7 over SYLVANIA 6ew7. It's more fine and detailed. Right now it's my Unicorn . I have a pair of RCA 6ew7 too, but i don't know if to try it with these because they are identical to a Sylvania 6ew7.

Raytheon or Westinghouse 6ew7, are they much better than GE?


Regards

Torero,

What type of music? I found the 6DE7 to have more impact and bass, especially with my Denon D2000's and rock/alternative. I am betting that you like jazz and/or classical with your K701's, and I would prefer the 6EW7 for that genre and phone myself. The 6EW7 has a bigger soundstage and is more seductive.

Are you using thin bottle or fat bottle Sylvania? I really like the fat bottle pair that I have.

I think the Westinghouse is a re-branded GE but the Raytheon is probably different. It would be worth trying a pair to see.

6 vs 6 SE Power Output

Jack gave me these power output specs for those who are interested.

WA6SE, 950mW per channel at 32 Ohms, 780mW per channel at 100 Ohms.

WA6, 380mW per channel at 32 Ohms, 200mW per channel at 100 Ohms.

I emailed him again for the 300 ohm spec. So far no response.

I have got :

RCA 6de7
Sylvania 6ew7 fat bottle
RCA 6ew7 fat bottle
GE 6ew7 fat bottle & clear-top

The question is: Which is the 6ew7 better?

I am running Sylvania 6DE7's and the Sophia 274B. This is an outstanding combination. The rectifier upgrade probably accounted for 80%+ improvement in soundstage, midrange and bass. The WA6 SE is an outstanding headphone amp. Yes, I have become a fanboy of Woo Audio and cannot see where one would need to spend significantly more money to achive such a fine sound.

I hate the term "fanboy", but I guess I'm in the same boat as you. I love Woo products immensely. I guess I'm a fanboy too.
