Woo Audio WA22 Amp Owner Unite

One other option for you I just tried for my 'noisy' outlet: The Audiolab DC Blocker and Mains filter, $129 at Amazon right now. Wow, this little box eliminated all hum for me when using a 'dirty' power outlet, even after turning on dimmers, TV, microwave, etc. throughout the house. I do not detect any negative impact on sound quality, on the contrary. I am sold and will get more. I clearly had a bit of DC in my line that transformers absolutely hate and respond to with hum. Give it a try.... free returns.

Thank you for your response but I have a clarifying question: did it eliminated the hum on your wa22 or your other high end equipment?

It eliminated the hum for the WA22. All my other equipment is plugged into a PS Audio P5 which is plugged into a dedicated power line. No hum there...

Just scored the awesome Cossor/Mullard GZ37 fat bottle rare rectifier (check out Dubstep Girl's rectifier thread). It's just as much of an upgrade from the mighty USAF that I was using before as she writes.

How do they sound?.

I have a similar set up with Mullard GZ32, Tung- Sol 6SL7 and TS 5998 and they sound very dynamic and detail,

Sounds really great. Tad warmer than the USAF one but I just got it like 40 minutes ago. Please allow me a little more time to form a more well-rounded impression. Although I am using Kenrad vt231s but I can surely post the differences. As of now, heavy metal music has less aggression to them. Which I find very pleasing though I won't say it's accurate cause the recordings themselves are shrill. Haha.

I thought I was looking at my amp because I have the same tubes at one point.

Anyone using WA22 with Arya? A quick search yielded no discussion. I'm debating between WA22 vs Cayin HA-6a to drive Arya.

I do but I don't have the Cayin. I imagine you'll get a more traditional wobbly tube sound off the Cayin as it has two modes (linear and triode). On triode mode you should get softer bass, less highs etc. But I wouldn't get the Cayin because tube amps are always a bit finicky - and they discontinued the HA-6A and Woo has amazing support.

Yes, and it is excellent. The Senn HD650 was my headphone for many years but the upgrade bug finally won out and I got an Arya about a year ago and am glad I did. I have no opinion on the Cayin but the thing with the WA22 is the sound is highly customizable based on your tube choices.

Hey folks, I might be pulling the trigger on this amp in a few days. How bad is the tube rolling market these days? I'm sure I'll be sticking with the stock tubes for a while, but at some point I'll definitely want to start rolling. Are the prices insane? Is there even good inventory at this point? I am VERY new to the world of tubes so this should be a fun ride...

If I am listening to my wa22 and the power randomly goes out can it mess the Amp or tubes up? Just curious?

It all depends on what tubes you want. You can buy cheaper tubes that will sound good but you can definitely spend some money if you shoot for the moon. I went ahead and did it big my first time. I had never heard tubes before when I bought the wa22 and I was wowed by the stock tubes. Once I rolled tubes to emission labs 5u4g mesh, western electric 421a, and mullard ecc35 6sl7 the sound of the wa22 was much better though. I spent another $1400 on tubes but it was a big improvement over the stock tubes and imo it was very worth it considering I listen with my wa22 90% of the time over my Soloist GT. I also enjoy WA22 preamp into the GT.

Hi Everyone. I’m happy to say that I’m part of the family. :)
My WA22 (2nd Gen) will be delivered tomorrow and in the meantime a really nice set of 6N13C (NOS). 1990. Sovtek power tubes came in mail just in time.


I’ll be running an all Soviet lineup of Sovtek and Tungsol.
Rectifier— Sovtek 5AR4
Power Tubes - Sovtek 6N13C (6AS7G) (NOS)
Driver Tubes— Tungsol 6SN7 GTB



I’m kinda cheating and ignoring the stock tubes and going straight to my upgraded set. I’m just too excited to hear the very best I have. Look forward to sharing my experiences and I happily read through this entire thread and man those Tungsol 5998 get some serious love here. One day I’ll try’em. I’ll just have to let my wallet cry once…hard! Lol
