A very rare and special amplifier is now available for sale
Halcro DM-38 Reference Class Stereo Power Amplifier
Traditional Solid State audio components of the past "tried too hard" with their exacting sound, to get the sound "right".
Almost every vacuum tube design, however, at almost any price range exhibited a magical bloom, body and harmonic texture that was somehow, ignored or truncated in solid state designs not so long ago. The very breath, space and air of the recording session was somewhat overshadowed by "spectacular speed and clarity"...the whole presentation was stripped of its humanity by most designs available!
Examine the technical information and philosophies of Halcro,
Viola Labs (Cello), Constellation, Boulder, Gryphon and Thrax (just to name a few) and you will become aware of similar patterns of thought in design and technology converging on a more involved, human-like sound/ feeling!
Regarding the sound of the mono version of this amplifier, Stereophile's Paul Bolin had this to say about the DM58
..."I have yet to hear any amplifier that equals the dm58's combination of complete neutrality, harmonic generosity, lightning reflexes, and a sense of boundless power that is difficult to describe,"...Paul Bolin summed up his experience with Halcro's dm58 monoblock.

Mated to naturally balanced, reference level components the non-sound of the DM38 is simply beyond reproach.
