Classic Audio Research SP-8 (with Phono) is the more desirable earlier version that:       "Audiophiles in the know want".

Very open and dynamic unlike most later ARC Pre Amplifiers.  Highly Recommend !

                                                Serial # 9312003


          Rated in 7/10 condition buy=t you will likely think they are a 8/10 !


             Uses 12AX7's, 6DJ8's and a 12BH7.

                               Comes in Factory Box & Manuel.

While testing it before posting this Classic Great Sounding Pre with Phono, we blown away how good it sounded next to our Store's Reference EAR 912 ! 

 Condition is very good and clean with only issue being some minor hard to see nicks on the top front edge (see pictures).

 All pots and switches function and are quiet.

Comes with original owner manual.
