Woo WA22 - Page 18

post #256 of 322
Got mine today. After an hour burnin with stock tubes couldn't resist anymore and took a listen.

OMG so much detail!

I used to enjoy the SR225, this amp really shows their limitations.

at 9:00 SR225 sounds like a shouty PA system. AKG701 much better at 11:00, HE-5 sublime at 2:00. More after burnin

Stock tubes:

SovteK 5Z4G
PhilipsECG 6080
GE 6SN7GTB

Can't wait to swap in the good tubes.

This amp really shines more with high impedance cans. Grado does not do justice for it.

But welcom to the club.

Looks like HE-5 is a keeper. SR225 goes to my daughter and AKG701 to WTS.

I really love my WA22 with my D7000s. It has absolutely no problem pushing these babies to their potential. One of my favorite things to do is watch the scene in Iron Man when he returns to Afghanistan and saves the family from being killed. When he shoots his palm lasers, the bass sounds absolutely freaking incredible. I almost get scared thinking my headphones will implode! The only thing I'm missing is the huge IMAX screen and a tub of popcorn.

Is anyone using their WA22 with the 4-pin XLR output? The one that says 'Stereo'? I was using the 3-pin XLR connections up until today. Having one plug is much simpler plus I'm able to get better strain relief, and it looks cleaner too. Sadly, I don't fall much for the placebo effect so I can't say that the sound quality has improved or decreased. Just throwing it out there since I very rarely hear anyone talking about using 4-pin XLRs.

Seamaster, I just sent an e-mail to TubesUSA about purchasing the 5U4G mesh! I'm so freaking excited.

Forgot to mention Denon D5000 and D7000. They sound great with WA22 (D7000 I tried), not so much with my Grado RS-1 through. I never been to Afghanistan, but Iraq. The bass was great when mortars came in, in pairs landed at next door. Big clean boom with alot of dust shook of my ceiling. Those were some really tight, clean and loud bass with impact force! Knock all the redbull and water bottles off from shelf.


Please note: EML 5U4G need 100 hours brun-in. I know, sucks to be you and me. They are well worth the money if you pair them with right driver tubes.

Ah man you were in Iraq? That must have been pretty wild.

George from TubesUSA sent a response within a few minutes; he said that they are expecting a shipment on Feb. 10th so he'll let me know when it comes in.

That does suck, but if the amp sounds this good with the stock tubes, I can't imagine how good it'll sound with the 5U4G. As they say... without the bitter, the sweet isn't as sweet.

As a side note, lately I've begun to hear some interference on the left side of my headphones. It's like a hissing crackle type of noise. I haven't had a chance to swap tubes yet but I'm guessing that one of my tubes could be starting to go bad. It's only on the left channel, and I can only hear it (since it's so low in volume) when nothing is playing. I'm sure it's not the amp because I only started to hear it a couple of weeks ago. It's not a constant noise either, which is why I think it's just a tube starting to die out. It randomly occurs and just lasts for a few seconds.

Try with 7236. It doubles the output and you don't need to turn up to 2 o'clock with HE-5.

I am eying that can also, so it's good to hear that WA22 drives them well..

Is your HE5 SE or balanced?

SE - getting the balanced cable (hopefully) this week. Will try the 7236 thanks!

I've also got the Tung-Sol 6AS7 and Chatham 6AS7 on the way and a bunch of 6SN7s to try.

I'm going slowly - so far replaced the stock Russian rectifier with a NU 1940s 5U4G - base is back in spades.

I got my WA22 today. Yay~.

Burning, burning, burning~~~~

Anyone using WA22 with their HD800 balanced/SE? If so, are you using HI or LO with it?
post #266 of 322
BTW, also tried out TF10vi with WA22 on Lo impedance setting with the stock tubes.

They sound little muddy with too much bass.

As for HD800, I tend to favor wit Hi setting so far..

Keep high with HD800. Low for cans like Grado

DO NOT RUN YOUR AMP WITHOUT HEADPHONE LOAD!!

Stock tubes are definitely muddy and tuuby.

So far I've replaced the rectifier and the power tubes. Each change has taken the amp to a new level. Going to replace the GE 6SN7GTB tonight.

P.S. The PhilipsECG 6080 are just atrocious.
My stocks are different than yours.

I got unamed rectififer. For 6SN7, I got GE. For 6080, I got RCA.

Cool.

i read somewhere that HD800 plays better with low impedance.

Must be with different amp..

Thanks for the tip. I am not brave enough to run w/o one. ;-)
