Audio Research SP-10 THE HOLY GRAIL (REDUCED)!

I have for sale an Audio Research SP-10 mk2 preamp. There is plenty of information on the internet regarding this famous preamp so I won't go into much detail. Basically, it's one of the finest preamps Audio Research ever made and one of the best ever!, with an excellent phono section and line stage for CD's. The layout is a dual mono design and it's also designed to accept most moving coil cartridges direct. If the moving coil cartridge is rated at 200-400 microvolts the unit can handle that cartridge without a step-up device. The preamp also has a bypass switch dedicated to the phono circuit where it bypasses all other circuits and feeds the phono section directly.
It's an all tube unit in both the power supply and audio sections. The unit is all original with no modifications. This Audio Research SP-10 mk2 is a classic tube preamp much like the Marantz 7 or Mcintosh C-22 (only much better sounding) and it will retain its value and increase over time.

all the Electrolytic filter capacitors were replaced within the past month along with Vishay foil resistors (the best in the world) in key areas within the line and phono stages. All Audio Research SP-10 preamps at this stage should have these filter caps replaced as they typically have a 20-25 year life span. This normally is a $700 expense which you won't have to worry about.
In addition, all the controls and tube sockets were cleaned. The tubes have all been tested and are all strong/excellent with an estimated 300 hours of use and will provide many years of use before a re-tube. This is a very late model of this preamp...it's an original mk2 version and the best way to tell is by looking at the eight 6dj8 tubes in the audio section, mk2 units will have a 4 inch long litz wire running from the third set of tubes back towards the back of the chassis.

Condition wise, it's in like excellent condition!
The preamp was never rack mounted. Everything works fine and the unit sounds great. The preamps entire life has been in a non-smoking, no pet household. A True legend, and collectable heirloom! Discounts for cash and local pick-up.
