I owned a Levinson #23 for several years, during which
time I used a Spectral DMC-10 among other preamps.
The #23 is a fairly neutral sounding amp. Some describe
it as "dark" though I do not agree. It has solid,
well-defined bass, good transient response, a moderately
broad soundstage and detailed high frequencies. It is
probably not the ultimate in transparency, but is quite
good in that respect. Overall, I enjoyed the #23 and only
sold it to purchase a #27.5 which is lower in output, but
somewhat more transparent and holographic in its presentation.
