Audio Research SP-20 Killer Headphone + Phono [Expired]


no longer for sale

The Audio Research SP-20 is highly desirable and collectible. It already has assumed the status of a audio icon. Up for sale is a perfect condition silver Audio Research SP20 pre-amp with phono and glorious built-in headphone amp. This unit is the best ARC preamp I have ever owned and the only one made by Audio Research with a headphone jack and killer headphone am built-in.  I'm simply moving to an all-hedphone setup and, accordingly, the ARC Sp20 and it mate, a silver Audio Research DS450 amp, are leaving for other discerning audiophiles. The ARC DS450 is being listed separately, but I am open to a package deal for both.
This preamp is flawless and carries a Class A rating in Stereophile. They rarely come available on Audiogon, so don't let this one get away.
I have the original packaging, remote, ARC manual and ARC screwdriver. I just retubed with an upgraded quad of matching Electro Harmonix gold pin premium tubes on last month. The receipt for the matching tubes will be included for your information.
