Meanwhile, over in the Purity Audio Design room, Bill Baker and Joe Jurzec were demoing their spanky new all-metal preamp chassis. Bill told me that the new chassis are significantly more robust than the outgoing acrylic trapezoids, and while they are, I kinda miss the oddball shape of the old design, which kinda reminded me of a sandcrawler (minus all the unsightly blast damage). New, along with the upgraded casework, is a tube circuit that features a 6SN7 tube, and the “power supplies now utilize high current toroidal transformers, choke filtering and 100% polypropylene capacitor filter banks.” Paired with the all-wood, asymmetrically-faced Argos loudspeaker from Daedalus Audio ($12,950), the impressive two-chassis Silver Statement preamp ($32k) was actually upstaged by another what’s-this-it’s-new offering – a rather sleek pair of very black parallel SET mono amps, based on the 300b tube. The $26k (est. pricing) prototypes, carrying the moniker PSE300b, were actually completed earlier that same week, but were very ready to shake the room with some astounding bass. Wasn’t expecting that out of a 300b! Other bits in the Ball Tech rack were a Playback Designs MPD-5 DAC ($13k), a Sony XA777ES (used as a transport), a digital cable from High Fidelity Cables, signal cables from Gingko Audio, and power cables from WyWires.
