If you know you know. I bought this thing earlier this year, installed it into my rack and never used it, In fact it has never been turned on. I had to put all of my musical endeavors on the back burner this year and this thing needs a new home and it needs to be used. It's flawless. Comes with original packaging box warranty card and power cable. Original purchase price with tax was around $3600. Save a couple bucks and take this beast home!
