For sale is a Decware CSP3 Two-Channel Single Ended Triode OTL Tube Headphone Amplifier/Preamplifier.  Less than a year old -- purchased in August 2015.  Most of that time it has been in storage (climate controlled, no pets or smoking).  

You can read all about this preamplifier/headphone amplifier at https://www.decware.com/newsite/CSP3.html.

This unit has the following add-ons:

Base Style:  Natural Oak $50

Volume Control:  Stepped Attenuator $150

Output Jack Configuration:  Dual Stereo $50

Signal Capacitors:  Cryo Beeswax $275

Headphone Jack Type:  1/4 inch + 4 pin XLR $75

Knob:  Gold Knob (the only choice with stepped attenuator)

I replaced the three (3) output tubes with audiophile Telefunken E88CC/6922 cryogenically treated and matched tubes that I purchased from Upscale Audio.  I doubt I have put more than twenty (20) hours on this unit.  The tubes are not even fully broken in.    

Over $2000 invested.  Will sacrifice for $1100 with professional packing & shipping.  Any questions, just ask.
