    We have been wondering if an SP-6C type circuit (as in the schematics above) could reach an even higher level of performance, given that the SP-6C's circuit and operating points are quite similar to the renowned vintage Marantz 7 preamplifier. But back to Ron's stock vintage Audio Research SP-6B.

The unit was in very good condition but badly in need of repair. This preamp had an above average power supply with 11 large twist-lok can capacitors.

I think it is very important to match the SP6 with a Audio Research amp.I bought a D52b amp used,and it simply sounds wonderful.Very smooth,extremly detailed,not overly bright.I agree the volume knob is sensitive.I see why
