Audio Research SP-9 mkIII [Expired]


no longer for sale

Factory built, babied, 1 owner, very light use, smoke free environment.

I’m unaware of any physical or performance flaws.

This is the factory-built 3rd generation version of the venerable SP9. ARC no longer upgrades earlier models to Mk III specs.

Reviews say things like

“a superb hybrid transistor/tube preamplifier”

“no surprise that so many other manufacturers’ products belatedly followed in its wake”

“excellent reliability”

“tremendous value”

“now a superb used bargain”

“purists will of course seek out a mint Mark I, but for daily use the SP9/III is the one to go for”

“find a good, well cared for example and you’ll never look back!”

Upgrades include

14 different improvements and 61 component and wire changes

use of M.I.T. capacitors at critical points in the circuitry

additional filter and bypass caps for the power supply

a new import board and improved grounding

gold-sleeved tube sockets

improved voltage regulation

6922 dual triode tubes

thicker front panel and rack handles

WHY SELLING

Downsized. Because there's no better space, one system is now in dining room. Not good – limits how much I use it, that space is not great acoustically, and I worry about damage there.

WHERE SELLING

Lower 48.

ABOUT SELLER Honest, ethical, dependable. Will only deal with same. Why just a few feedbacks here or elsewhere? (3 for 3 positive on US Audio Mart - username MissingTucker)  I’m a buy and hold guy. Bought a system 25-30 years ago. Life evolved. Bought a second one ~15 years ago. Now downsized. Will keep one system.
