Rare opportunity to own a bespoke custom made, point-to-point wired David Berning Co. octal pure vacuum tube preamplifier with built in passive RIAA phono section section and outboard resonant switching vacuum tube power supply.  Unlike Berning's later preamp offerings, this is a capacitance coupled design offering even greater midrange weight, palpability and body.  Features many hand selected upgrades and component options.  The line stage features NOS 6SN7 octal vacuum tubes with NOS 12SF5 tubes in the phono section.  Playback is dynamic, clear and lively, offering a true 3D holographic dimensionality, with solid imaging and an open, grain free musicality with simply wonderful timbre and tonal characteristics.  As an octal tube based design, this Berning Preamp requires a high quality, heavy, high mass equipment rack to perform at its best.
