Most “disappeared” speakers.

I am chuffed to bits with mine an ex dem pair of Piega Classic 40.2. Superb ribbon tweeter which just gets the music right. I use these with valve amplifiers which really assist with the staging. Prior to these I found Living Voice did a reasonable job. However the Piega also pass the wife test which is important. 

Boenicke W5 can do this well. Also have impressive bass för being so small. 

I agree that Audio-Physics are also good at this.

EASY-PEASY:  Anything Magnepan SET-UP correctly with quality electronics.  (You only hear what you enter into them, good or bad.)

RE: poster who suggested horn speakers.  PLEASE listen to ANY properly set-up horn speaker next to a set of properly set-up Maggies of pretty much any era.  You may not change your mind, but I kinda think you will.  Be sure to listen to your favorite music on both.

Cheers!

Harbeth P3esr 40th anniversary with a good sub and near field listening has been what's floating my boat lately. Steve Guttenberg says they disappear more then almost any other speaker he's heard, he comments on them all the time on how good they are.
