ON SALE AGAIN, SIGNIFICANT PRICE REDUCTION. Still been in the boxes, unused, since shortly after purchase.

Putting my new WA234 monoblocks on the market, ordered in March, just got them two weeks ago. (Yes, they take more than 3 months to build, not 6-8 weeks.) This is purely for financial reasons, there is nothing wrong with the amp, it sounds spectacular. I overextended myself buying this and am happy to live with my WA5 instead. But I don't HAVE to sell so low-ball bids will be ignored. I am prepared to sell instantly if I get a good offer, though. MSRP is $16k, specs are here:

https://wooaudio.com/amplifiers/wa234mono

Only change I made from the default specs is to substitute 6SN7 driver tubes for 13EM7s. (Originally I also wanted the XLR inputs to bypass the volume controls but decided not to do that.) Some may know that the first iteration of the WA234s actually came with 6SN7s and Woo changed it to better accommodate the power needs of speakers. I don't care about speakers though and this amp has more than enough power for any headphones. (I use Plate LO-Z for the Abyss-TC. Plate HI-Z gives even more power, but for what... maybe the Susvara?)

Also, the stepped attenuators that Woo previously used for the volume controls have been replaced with ALPS RK50s. This is not a special request by me, it is a design change going forward. At first thought you'd think it would be annoying keeping two channels in balance using a pot, but I found it surprisingly easy. Typical use case is to set the pots at some reasonable value, then use an external quality pre-amp to fine-tune (I used my Benchmark HPA4.)

Amp is near-perfect cosmetically. I won't promise I didn't make some tiny scratch or nick but I cannot see anything.

Amp comes with a 3-year warranty and it is transferrable in the first year, so you will be getting this warranty.

Amp comes with the stock tubes (nothing to write home about) and the wooden suitcase containing the "keys" that let you choose output tube and gain. Amp also comes with a custom 3-pin XLR male dual to 4-pin XLR female single adapter I bought from Double Helix cables. No power cables are included.

Blocks have 110v/230v jumpers on the back so they can be used in other countries.

Amp is currently boxed up and not being used to preserve its condition.

Shipping will not be cheap. Amp is located in California Bay Area (local pickup is possible). I will ship international, but I will NOT under-declare the value to customs, please don't ask. Here are the dimensions and weights of the 3 boxes so you can calculate the cost for yourself:

Box 1: 19x16x14 inches, 70 pounds
Box 2: same as box 1
Box 3: 18x14x11, 15 pounds

Have you tried to power floorstanding speakers with this (like B&W 803D)? How’s it?
No, I'm not into 2-channel at all. I think it can do 8 wpc into speakers with 300Bs which is somewhat standard for SET amps, so you need very sensitive speakers.

Numbers are often misleading for tube amps. An entry level like Decware SE84UFO can power giant floor standing speakers with ease. It’d be cool if you or someone could demo this amp on big B&W or Sonus Faber speakers.

Interesting!
Could I convince you to give us some pictures of the internals? I've always wondered.
Using a Nautilus currently. I'm in the Bay Area.

Not clear how to open this up, it's built very differently from a normal amp with lots of aluminum plates and all the screws I can see are on the bottom. Don't want to risk the warranty.

Sorry to hear you have to sell. I think we should start a Go Fund Me page so you can keep them.:jecklinsmile: Absolutely beautiful amp. I would consider it, but I just bought a new sports car and my headphone fund has taken a serious hit.

I can confirm this 234MONO was recently delivered. It took longer than expected to build. Warranty is 3 yrs, transferable on the 1st year from the original purchaser.

I like the 6SN7 driver tube because there are many great sounding NOS tubes on the market and the 5692 tube can be use which is the best 6SN7 alternative. But that's just my personal opinion....

On sale again. Have not been used any more since the above, they are still in their boxes. Significant price reduction. Gotta move these now.

It is amazing this amp is not the most expensive amp for sale on this forum right now

I also have a pair of PSVANE ACME 2A3s and a pair of Emission Labs 2A3s I purchased new along with the amp. I'll sell them half-price to the buyer of this amp as a separate transaction if they want them, I have no other amp that uses 2A3s.
