Audio Research I/50 Integrated Tube Amp Black w/ DAC + PHONO Modules

I am selling my like new black I/50 integrated amp by audio research. I am the original owner of it. It comes exactly as it would if you bought it brand new. This is the most desirable color and speced out unit in my opinion as it comes with both the $1200-1500 (?) DAC upgrade (which sounds AMAZING) and the same $1200-1500 Phono Card Upgrade. This maxes out the potential of the unit and its in a sleek black color which I liked most. There are a few hundred hours on it total as it was a 3rd system for me so its literally perfectly broken in and sounds wonderful. Its a deceptively small system but when I plugged it into my Wilson Sasha 2 speakers it powered them with ample amounts of power and sounded great there and it also made these Tannoy System 1000 speakers that I used with them sound excellent as well. Due to the condition, # of hours and options I priced it at $5500 which I feel is fair since its $7500 brand new. I'm open to serious offers on it and can ship quickly.

As a side note, I have some cables for sale that include bi wire Synergistic Research Speaker Cables with the active shielding, maybe a SR RCA interconnect atmosphere level 2, SR Purple Fuse for the unit, SR MIG 2.0s, Tannoy System 1000 Studio Monitor Speakers (MADE IN UK) and a Richard Grey power block 400 unit in case anybody has any interest in those.
