I created this buffer amp for use between your DAC or other digital audio device and you pre-amp. It can also be used between your CD player and your system. The benefit of using this unit is to take the music signal and better match it for the input of the pre-amp. Sonically, it removes much of the digital hash associated with digital audio. I am pleased to say that is very clear sounding, and makes recordings a pleasure to listen to. No it won't fix a troubled system, but rather enhance an already good system............
It sports two separate power supplies that feed both the tube heater and audio circuit. Each power supply is regulated, meaning that whether or not the incoming AC line voltage is accurate or not, the regulated circuit keeps it at a steady voltage....................Being able to switch each part of the power supply on one at a time , gives the tube a chance to heat up first, before accepting the high voltage from the main power supply. This results in longer tube life, and is used by other high end audio companies in the form of 'soft start' or 'standby' modes.
The two tube towers are very kool looking, and have the added benefit of shielding the tubes from RF noise and interference. Each tower is a machined tube that is also finely threaded holding the tube securely in place...................
RCA connectors are manufactured by Manley Labs, who manufacture high end studio equipment and home audio. .............
This component easily and quickly became my favorite tube buffer, and so I made one more for myself. That really makes this a limited series!

As always, I encourage any questions about this unit, as well as audio in general.

NOTE: I am adding a second set of tubes in the sale. A pair of SOVTEK tubes from the Tube Store, NIB
