I haven not heard one, but Bench said that it sounds very, very good. Having seen the quality of Bench's designs over time and hearing Bench's very high regard for this design, I trust that this design would sound very good. The advantage of this design is using the tube in single ended operation while it is in its inverted mode, resulting in a very linear tube curve. Linear tube curves, of course, means very low distortion. The other advantage is very low power draw for the amp. As you point out, you would need efficient speakers for this amp to qualify, or a lot of output tubes (which are not expensive).
Bench went out of the way to avoid any iron, but I would think hard about using very high quality interstage transformers versus the coupling caps shown in this design.
