Hi mate, cheers. To answer your questions in order...definitely and probably :-)

After a couple of hours listening, straight out of the box I'm finding the WA22 very impressive indeed. I still maintain that the Mapletree Ear+ is a great value amp, but this really takes things up a few notches. I'm hearing a similar amount of slam & control I heard with the Headroom UDAC/BUDA combo driving my balanced HD800s, but now I also have that lovely tube richness of tone that I missed with the Headroom rig. Memory is such an unreliable thing, but I also suspect the soundstage of the WA22 is wider as well. Without a doubt I am enjoying the music more, and that's good enough for me.

So far, this is giving me exactly what I was hoping for, and is precisely why I went to the trouble and expense of returning the UDAC/BUDA/DPS (international shipping). It's also impossible not to grin when I look at that EML 5U4G glowing away in all it's glory . The WA22 with these tubes also has a gobfull of power. I mean, serious power. On "low" setting, at volume position 7 of 24, it's driving my balanced HD800s as loud as I can comfortably cope with. On "hi", the more appropriate setting in theory for the hd800, you can bring that down another step. I think the Sylvania power tubes I'm using more than double the stock output, and actually it does mean the volume steps are quite large. Some may well find they can't get the precise volume they want in this configuration.

One thing I've noticed, when powering on the WA22, if I turn it straight around to the "low" setting (past "hi"), it trips my electrical circuit every time. If I leave it in "hi" until the soft start completes & then move the dial to "low", it's all fine. I've emailed Jack for confirmation on why this might be, but there certainly shouldn't be anything wrong with the circuit in this room as it copes with 3000+ watts of home cinema system quite happily. I'm wondering if this is why there are two "off" positions, on far left and right on the dial.

My understanding is to not spin the knob 260 degrees around, and only switch from lo to hi or back after the amp is powered up, at least with the prototype.

Yep, that makes sense considering what I'm seeing. Cheers.

What was your wait time for your amp? I ordered mine 3 weeks ago and build time was estimated at 7 weeks. When I inquired a week earlier prior to my order, it was 5 weeks. Jack must have gotten lots of recent orders.

Just ordered my wa22 on 11/5. Can't wait. =)))

PS DL3 + Cullen3 -> wa22 -> HE-5 | K701 | SR225

What are the favorite tubes for WA22 so far?

Seems like EML is the favorite rectifier.. and sylvania 7236 for power tubes.

What other driver tubes? Any of you ordered/using Shuguang Treasure series? or are you guys using something else?

Finally managed to get my WA22 plugged in to burn in for a bit







Won't have impressions for a bit until I can try on some different phones.

That Sophia looks darn good! Guess you got sylvania 7236 also?

Yes. Also ordered AMPEREX GZ34 and pair of Mazda 6CG7/6FQ7 to play with after reading about Seamasters tuberolling.

Yes, you owe us impressions too. bro

pedalhead: Glad to hear you are enjoying the Woo and thanks for the quick impressions.
post #179 of 322
Thanks Shelly, no regrets at all going with the Woo. For those looking at tube rolling options, Seamaster has been doing some great legwork for us, detailed in a couple of other threads. I've got some Rytheon 6F8G and Mazda 6CG7 waiting on some adapters to try. I can certainly say that the Sylvania 7236 NOS tubes Jack provides as an upgrade do provide an improvement in soundstage & detail over the stock GE power tubes. On the other hand, I rather regret spending the $$$ on the Shuguang CV181-Z driver tubes as I really don't feel they provide an improvement over the stock Morotola 6SN7s. Still, it's all a learning process isn't it. Oh, one thing with the Sylvania 7236 power tubes...they do up the output considerably, to the point where some might struggle to achieve an ideal volume on the stepped pot, depending on your headphones. I can't go any louder than five steps up with my balanced HD800s, and in fact I would say my ideal volume would be 4 and a half...but I can live with that .

me too, I am very happy with WA22 for now.

For Shuguang CV181-Z I knew that is going to happen like that, I feel very sorry you to spend all that money on them.

As Rytheon 6F8G and Mazda 6CG7 will kick Morotola 6SN7s out of water, I guarantee. When the last time you heard form Glenn?
