- Putting my new WA234 monoblocks on the market, ordered in March, got them July. (Yes, they take more than 3 months to build, not 6-8 weeks.) I used them for a few days then boxed them up again. 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.
- From the manufacturer: "The WA234-Mono is the ultimate SET (single-ended triode) amplifier. The design is unlike any that the world has ever seen. The WA 234 unique design allows for us of legendary tubes like the 300B, 2A3 and 45 triodes. The choice of tubes offers the highest level of transparency and musicality. The WA234-Mono let you experience music like never before. You can now use any headphone and many high efficiency speakers. Whereas a typical tube amplifier allows you to use only one type of power tube (or a substitute with a similar rating), the 234-MONO increases your options in an elegant way. A tube-switching key (TSK) allows the amplifier to accept 2A3, 300B, or 45 power tubes, so you can instantly switch your tube to suit your music or your mood."
- 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.)
- I don't have a history on Audiogon but I have an extensive posting history on Head-Fi under the same username, so I am not an unknown quantity.
- 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.
- I am serious about this being in mint condition. Amp is back in its boxes now, not being used.
- Blocks have 110v/230v jumpers on the back so they can be used in other countries.
- Amp is located in California Bay Area (local pickup is possible).
