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. What's the difference between the two AR pre-amps? Is the sp 11 that much better than the 10? TIA

The Sp - 10 (either 1st run or Mk II version) is a better preamp than the SP 11, which is also a very capable unit. imho the Sp 10, is followed by the Sp 15 and then perhaps the Sp11. All are wonderful performers.

I have a SP10II. wouldn't part with it - bought it around 1984 and it has been the core of my system ever since. When the SP11 II came around I found it to be brighter (some people read this as more detailed). The only problem with an SP10 is it needs quiet tubes. If the SP10 on EBAY isn't a II plan to have ARC do an upgrade - its really worth the difference. The phono stage is worth the price of admission alone. Excuse the testimonial, I just couldn't resist.
