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.

Review: Audio Research SP-6b Tube preamp
https://forum.audiogon.com/discussions/review-audio-research-sp-6b-tube-preamp
