Thanks. I've been eyeing both the Elrog and the EML, but I can't find them in stock anywhere to buy right now. Rather annoying, but it is what it is. I have been going through lots of those other tube threads. Lots to read!

Send emails to customer service at Parts Connexion and Audio Art respectively. They're usually very quick to respond and will get your stuff fairly quickly. I think I waited all of three weeks to get my Elrog 5U4G's from PC. About a month for the EML's.

The other main new feature was XLR pre-amp outputs.

Does anyone have any internal pics comparing Gen1 to Gen2?

I have a Gen2 from March 2022, and curious about how they compare internally.

Gen. 1

My Gen 2

This is a totally stock Gen 1 WA22, September 2015 build. The PCBs have 2014 revision dates...

Not quite stock, that volume pot is a motorized remote Alps version.

As built by Woo with no extras/options... A Frankenstein? I think this is why posting photos and a build date makes it interesting. Perhaps they had part constraints? Hope some more internal photos get posted. Love the design. Better part of seven years in service and still like new in every way.

I read of at least one buyer that paid Woo to install a remote volume pot, perhaps this was one of them.

Unless this is yours and you are the 1st owner, then probably they just used the parts they had available at the time. It’s still the same quality volume pot, it just has the optional motor on it.

Also, it was stock at a certain point, but the original Gen1 doesn't have the phase splitters. Not sure about the year they introduced that change.

The Phase Splitter was introduced at some point in 2014.

I am the original owner. Had a local shop I support order a bare bones WA22 from Woo for me and I picked it up, unopened, the day it arrived. First time the cover came off was yesterday to take some internal photos...

In regard to the phase splitter here is a cropped shot. Date on the phase splitter PCB, version 2.0, is 140922. The power supply PCB 140527. Seems there might be a few iterations of what is more broadly known as the Gen 1 amp. Those who are buying previously enjoyed kit might want internal shots before making a purchase decision.

Do any of you know how to interpret the serial numbers on the Woo WA22? Not sure if the serial corresponds to year, date, or anything that could denote date of manufacture.

First two digits = month, second two = year. My WA22 is 0915XXX or September 2015.

Does anyone have any experience with the WA22 and really low impedance planars like the DCA Stealth or LCD-5?

I'm using the HE-500 (38ohm) and also the HE-5xx (18 ohms).

 

[muckyfingers]

Woo gives a rating of 1.5w at 32ohms. I’m curious about anything lower. How does the HE-5XX sound?

I’ve listened to the Aeon 1,2, and Ether 2 through a OTL amps, in the past. The result was that low volume sounded fine, but as you went up the dial, the treble became screetchy and the bass sounded like a blown woofer.
