What are some of the most underrated and overrated loudspeakers you’ve auditioned?

Over-rated -
Avalons - Flat, Boring, makes all music sound homogenous
Martin Logan - I really want to like them, but the sound on more complex music always loses it's cohesion

Under-rated -
Dunlavy (RIP) - people always focused on "cheap parts"The Living Voice - Amazingly fluid

Most underrated Klipsch RP-260f without a doubt.

I must agree with those who consider the Golden Ear products overrated.

They get a lot of mileage and street cred from the great sonics of the folded ribbon tweeter, which is superb, producing great clarity and detail resolution, which also adds to their great soundstage and imaging... BUT (there’s always a but)... their mids and bass are veiled and do not possess the same dynamics, speed, texture, clarity and detail resolution... say as... many of the underrated speakers such as: Proac’s, or Legacy’s (especially the Aeris and Focus), or ATC’s, or Tannoy’s, or JBL’s, or Linkwitz Orions / LX521’s, or Quad ESL 57’s (divine when properly set up and amped), or even Maggies, or my little known favorite... the Wavetouch Audio Grand Tetons / Anteros (true giant killers).

Now... this is all in the context of 2 channel acoustic, jazz, classical, country sounds (i.e. guitar, piano, double bass, cello, violin, sax, trumpet, brushes on cymbals, etc., etc.).

Avanti1960s list - perfect!
