Audio Research SP-20

Selling my beloved ARC SP20 preamp, original owner, smoke- and pet free home. The condition is a solid 10/10 mint, but since its over 1 year of age I have marked it as 9.

This pre-amplifier from Audio Research combines three products under one hood (Preamp, phono stage, and headphone amp) which is a rarity from this company. The tubes are original Sovtek from the factory, and are low time due the unit not serving a purpose in my system after I purchased a streamer/DAC, which was powerful enough to drive my amp. However, it was difficult for me to separate from this unit, as it really is a sonically great sounding product at a price point, that bests everything else I have heard. Unfortunately, I can't justify it sitting on my shelf without getting any use out of it - so the opportunity to make someone else happy is now. The tubes are just over 1,000hrs (barely broken in). This unit sounds incredibly clean with a THD of only 0.003% for the line stage XLR output, but please refer to the links below for better explanation of its full sonic capabilities.

I have re-packaged it back in its original box, with the manual, remote, power chord, tube-protector case, and everything else just as I received it from new - ready to go!
