Best midrange on SS amp ?

Well,
the Symphonic Line and BAT is nothing more than just a popular name. You should really try BVaudio power amplifier as you can see at this review

BVaudio bettered BAT big time. No hum, no hiss or any kind of this "el cheapo" amp design problem. BVaudio is death quiet, only music, nothing else.
you might look at their web to find more.

Consider the GamuT 250 monoblocks. GamuT amps are among the most accurate and musical sounding.

Another vote for the GamuT line. Very musical amp. Excellent in the midrange

Another vote for BVAUDIO. Hearing is believing.
