The Audio Research SP12 was the contemporary of the SP8 and SP10, and was their "budget" preamplifier- I think it was about $800 less than an SP8- that's over 1/3 less-a significant proportion. It was also, with the SP10, the first 6DJ8 based Audio Research preamp.

The SP-11 is a design departure for Audio Research. Like the Berning TF-10, it is neither a tube nor a solid-state preamp; rather, it is both at once. Each active stage is a combination of a triode tube and a FET—devices whose dynamic transfer (input/output) characteristics just happen to be very close to complementary.

The SP14 preamp is such a product. The last Audio Research product to grace the pages of Stereophile was the original SP9 preamp, which got a rather lukewarm review at the hands of both J. Gordon Holt and John Atkinson (Vol.10 No.8). That was 2½ years ago! A follow-up to that review is in progress; only the flagship SP15 preamp now remains a ...

5. ★★★★★. ★★★★★. [Dec 28, 2012] AudioBuff. Audio Enthusiast. I got a steal on this pristine condition ARC SP4 while shopping for a sub $500 option as a backup preamp. Not having experienced any ARC products before, I was completely amazed at the build quality, fit and finish considering that this was a product from the 70s.

Audio Research sp 11 compared to the sp 10 Am looking for an AR sp 11, but have had no luck. There's a sp 10 on ebay (plus a sp 11 that has four days left) The sp 10 is still under $1100 with time to run out tomorrow.

The Juicy Musics are great for the money but still out of my range so I started looking into used Audio Research pre-amps and Line stages. My amplifier is an Audio Research D-115 tube amp. The SP-8 pre amp was my first choice because it was built during the same era as my amp. They are hard to find under a grand.
