I don't think the ARC SP-11 Mk II pre-amp is dated. A pre-amp that sounds right and natuaral, just like the real thing. How can such a "correct pre-amp get dated"?
In my opinion, the golden age(from 1985-1993) of pre-amp is already gone. Most of the best sounding pre-amps are from that era, like the ARC SP-10, SP-11, CJ P7, MFA MC-Reference etc.
I bought a ARC Ref 1 about a year ago in Audiogon. It replaced my ARC SP-11 MkII for only 5 hours. Then I packed it and sold the Ref 1 the next day.
