The Class A Purity preamp below started out to be our Purity linestage before we moved on to having both a Reference and Statement Purity so this unit has a few features from both versions.
Details about this unit:
** Full dual mono power supply located in the bottom of the dual chamber chassis
** The outer chassis is more of a shell with a dual chamber cassette that is inserted from the rear.
** Jensen input and output balanced transformers
** Two pair balanced inputs / Two pair single ended inputs
** Two pair balanced outputs / Two pair single ended outputs
** ClarityCap ESA 22uF coupling capacitors.
** Custom Gold Point stepped attenuator with Bent Audio stepped remote motor (remote volume)
** Silver plated copper signal wire
** All RCA connectors will be replaced with Cardas pieces
** Cryo treated silver IEC
** Cryo treadted silver fuse holders (one per channel)
** Seperate dedicated power supply for the remote motor including a dedicated transformer.
** High and low output gain switch
** And More
** The outer chassis constructed of Baltic Birch Ply varying in thickness from 3/4" to 1-1/2" then painted a gloss black
** Inner cassette chassis constructed of 1/2" BBP making for 2" thick side panels.
** The control knobs are 1-1/2" Solid Bubinga
** Chassis was intended for evaluation purpuses so is not what I would call 'perfect' but the circuit is 100% and dead quiet.
This Purity has been used in our showroom as a reference preamp while we finished up on the production Purity design as shown in the last picture below.
Original retail cost would have been $13,000
Selling this unit for $4,250 + shipping.
