It sounds expensive. It has the traits of the finest components and places the sound at the service of the music. The sound stage is neither forward nor laid back, it is just there. Soundstaging is superb. When listening to voices, you will not hear a slurring that almost all solid state amps impart.
Voices are rich and full.
So are instruments. Even the McCormack amps sounds forward but has a similiar tube like quality which gives it a certain smoothness. However, it does not deliver sound as easily as the Audio Analog combo. It is much too refined for that. Rock always sounds better with a forward sounding unit and who cares about the roughness,edge and so on.
