Selling my WA234 MKII Mono Block Headphone/Speaker amplifiers; I am rationalizing my headphone setup to a single DAC/amp and headphone (hence re-opening the listing).
This version has the 42-position stepped attenuators, so level matching channels is easy and there is plenty of granularity and volume range.
They are in like-new condition, with no scratches, dings, dents, scuffs, nor any other marks I can see, and have always been kept in a smoke, pet and child free home.
You can read on, below, for more details about this very powerful, flexible, and amazing-sounding amplifier (or you can look at the product page at Woo Audio).
I’ll post additional pictures, of my actual amplifiers, when I get a serious inquiry.
Includes:
I would strongly prefer a local sale on this unit, due to the size, weight, and fact it is in three separate boxes. I will ship it, under the right circumstances and with the right buyer. Note that price does not include fees or shipping.
If you're local, or coming through Miami, its easy to arrange auditioning it.
Price is net to me, and firm.
Not looking for trades.
I have some optional tubes that I'll sell with this unit (or separately, after the amp has sold):

This is a true class-A, SET, transformer-coupled mono-block amplifier. Volume is set individually on each channel using a 42-position stepped attenuator (so it’s easy to match levels between left and right channels). You can also set volume to maximum to bypass the resistors and use a variable-output source to control the volume instead.
It uses 1x 13EM7 driver tube and 1x 5U4G/274B rectifier tube per amplifier, and your choice of 2A3, 300B or 45 series power-tubes. You can select either plate (high power) or cathode (lo power) drive, and high or low impedance output. These features are selected by inserting “switching keys” into sockets on the top of the amplifier.
It has plenty of power for every headphone I’m aware of, including the AB-1266 Phi TC (8.2W into 47 ohms, at 127.2 dB/SPL) and the Susvara (6.5W into 60 ohms, at 121.1 dB/SPL), while still easily handling low impedance cans, all the way down to things like the LCD-5 and Stealth at ~14 ohms).
I’ve used it to drive the RAAL SR1a via the TI-1a interface from the WA234’s speaker taps, to excellent effect.
8W of SET power is available to drive speakers.
They have 2x RCA and 1x XLR inputs, and 3-pin XLR and ¼” TRS combo outputs.
