The M-2b is a two channel, high voltage, transformerless, 100% Class A biased, all vacuum tube stereo microphone preamplifier delivering the essential nature of triode musicality.
The advanced M-2b circuits employ differential topologies, ultra-high headroom, electrically correct transformerless coupling, high voltage rails, hand-selected componentry, unfailing attention to power and ground integrity, and much more.
Why a vacuum tube mic preamplifier All audio circuits, regardless of topology, whether tube or solid state, impart some coloration. In all topologies, Millennia seeks to minimize circuit-induced artifacts while retaining as much original sonic information as possible at the output. Nevertheless, even in these refined tube and solid-state topologies, there remain subtle sonic distinctions. If we were to subjectively characterize our vacuum tube topologies, some descriptions which come to mind include a heightened sense of ambience and "euphonic space," a subtle but enhanced musical "sweetness," and a particular quality of "intimacy" not normally associated with our solid-state designs. By contrast, one might say that Millennia's range of semiconductor products (HV-3, Mixing Suite, TT-FET paths, etc.) present a tactile, acoustically lifelike rendition of even the most difficult and complex spectra, exceptional dynamic stability, and superior objective performance in areas of THD, common mode rejection, noise, frequency response, and output drive capability.
Alas, both Millennia design topologies (vacuum tube and solid state) offer incredible realism, yet each technique approaches accuracy from a different sonic direction. Vacuum tubes offer audio performance which semiconductors cannot. Semiconductors offer audio performance which vacuum tubes cannot. Both have a significant and complimentary role in professional audio. Millennia now makes available the finest in both worlds.
