What’s the most underrated used Audio Research gear?

Sure, everyone loves the SP-8, SP-10, etc., but what about the sleeper ARC gear that’s still a good deal used? Recently got a used SP-17 and love everything about it for the price, but it got no love from either the press or the boards.

sp11 a very good ARC tube pre-amp value IMHO,   Enjoyed one for many years.

SP 14, advertised as better than the sp-9, based on sp-15 technology.

Dual 76B and SP3-A-1. Much magic there. Especially when used to drive Maggie Tympani IIIs.
