Nor are they a good idea ;) That said it looks like they are using them as summing transformers for single ended output similar to what Woo does with the WA22.
In other news, I got a Metrum Octave a few weeks back and its good. Its not shall we say miles ahead from the W4S DAC-2 but its is better. The improvements are mostly in treble resolution, separation, pin point imaging and a more natural decay. Different tonal focus as well. If the Metrum is tonally balanced, the W4S is shifted downwards. Despite which in contrast makes the W4S sound shouty, edgy and missing sustain.
I use the AP2 now, which increases the bass punch and weight and further increased the image focus. Which on the W4S just crosses into shouty and fatiguing.
All in all a good buy. And something I didn't expect is so far, I prefer 44K native to 96K oversampled. Go figure.
