1915. Marcel Duchamp's nude has already descended the staircase, Arnold Schoenberg's Three Orchestral Pieces, Op.16 have shattered tonality, and the old order is crumbling. It is in this context that 30-year old Alban Berg completes his Three Pieces for Orchestra, Op.6, which is now available as the San Francisco Symphony's first download-only release in resolutions up to 24/192.

The KSL ($1800, $2100 with phono section) is a one-box line controller/preamplifier, just 2.25" high, with a nominal voltage gain of 10dB, or 3x. Despite its moderate price, the KSL is distinguished by having balanced outputs (via industry-standard XLR connectors), as well as two balanced inputs. Conventional single-ended, unbalanced outputs are also available via a pair of gold-plated phono sockets. Two unbalanced inputs are provided, plus a third via the tape monitor switch.

One of Crystal Clear's earlier releases (1978), this has very distant, directionally vague sound, but the sound (stupendous by standards of only a few years ago) cannot stand in the way of two of the most exciting performances of these potboilers that have ever been committed to disc.

Lots of in-the-moment twists and turns and a general sense of going with what felt right.

The issue is this business of "single-speaker" listening and demonstration, which has become fashionable in the UK.

The premise: bringing a second pair of loudspeakers into your auditioning room upsets the sound of the pair you're listening so badly that the first speaker's ability to correctly reproduce the timbre of musical instruments is destroyed. This observation is almost surely correct.
