Aric Audio Custom 6SN7 Line-stage

Up for your consideration is a custom 6SN7-based line=stage that I built recently for my own personal use. This preamplifier is very similar to my "Special 6SN7 Line", but with several upgrades that bring its level of performance to a higher level. It features a Khozmo 64 step relay-based remote volume control with digital display,
 I changed the capacitors out to Miflex KPCU copper foil and oil coupling capacitors for a more organic, rich sound and also use a walnut/cherry layered hand-build hardwood chassis. 
Other features include choke-filtering and all film capacitors in the power supply, a DC coupled input stage fed into a low impedance output cathode follower (output impedance is 300 ohms), a 50 kohm input impedance, and variable gain control on the rear of the unit for a gain of up to 20 db and variable down from there to zero. 4 sets of stereo inputs and 2 sets of paralleled outputs for connecting to an amplifier and subwoofer, or two amplifiers, copper shielding inside of the chassis, and all copper wiring used throughout.
 I will provide a set of NOS Sylvania 6SN7GTAs, a NOS RCA 5U4GB rectifier and a pair of RCA OD3 regulator tubes. The remote volume controller uses shunt resistors and uses relays to engage the 64 steps of attenuation/boost. Each step mutes the volume to 50% of the desired setting for a millisecond to avoid audible "clicks" when the relays are engaged. This is a very high end remote controller system.
 This unit has a 2 year warranty provided by myself, the designer and builder of the unit.
