Driven by the Triode Corporation Japan's TRV-M300SE 20W 300B parallel single-ended monoblocks ($4199/pair) and TRV-4SE tube preamp ($1799), and fed by a very-slow-to-cue dCS SACD player, the Cain&Cain Wall-O-Sound (W3) ($3300), designed by Gordon Rankin of Wavelength Audio, did a superb job reproducing the true timbre of a piano. Throwing a huge soundstage, with wonderful height and depth, this little system had me writing "really beautiful" in my notebook.
