The sound is clear, rather transparent, precise, detailed, with that specific "lucid" presentation typical of triode units.
Low frequencies are well present and controlled, even though perhaps not as much as you would expect from an amplifer with a damping factor of 400. The entire bass range is definitely round and full, pleasant and effective, exactly as it happens with many tubed amp systems.
Mid range is clean and smooth, not especially in evidence, but enough to give voices the correct body and appearance.
High frequencies are open, clear, lucid, really tubey. Given these qualities, the unit does not forgive sources with a "digital" flavour in the sound! In such a case the sound becomes rather "viscid", unnatural and as such unpleasant. Otherwise, it is limpid and smooth.
