Refurbed Walnut Advents - Most affordable option, easy to find. Grab a nice pair and enjoy while looking for something a doctor or orthodontist would actually have bought with a 2270.. ADS L-810 I'm probably the millionth vote for these, but there's a good reason - there and are extraordinary speakers. JBL? L-110 definitely, L-65 Jubal, maybe. NOT the L-100 or worse, L-36. They were harsh, boomy, and didn't image at all. The L-110 was the first JBL to use proper Thiele-Small parameters to design the porting, and as a result,, the first JBL with extended, well defined bass. They were also the first JBLs to use a modern soft dome tweeter. the were one of the few boxes that could hang with the L-810, were built better and not at all fragile lIke the ADS (tweeters).Klipsches of that era were simply horrid soundibf Build quality on the Rectilinears was...garage level at best. Allison 1 and Dahlquist DQ-10 both had interesting acoustical stories to tell and could sound great but had very specific and non-negotiable setup requirements. The Allison's had to be against a wall with at least 3-4 ft clear one the side. Dahlquists had to be 3 ft out into the room. Yamaha NS-100Ms are great, but putting them with a Marantz is kinda committing a Chevy engine in a Ford chassis foul.
I was there when the 2270 was at it's unassailable peak as an aspirational receiver. I sold most of those speaker models and have hundreds of hours listening to them, both in our showrooms, and at home, so I think I come by my opinions pretty honestly.
