Speakers known for great midrange.

Wilson Audio Duette.

Salk audio Exotica Raal Monitors.  I use them with a Pass XA - 25.

I must agree with the comments about Harbeth speakers - which have great rich midrange, well controlled bass and superbly clear, smooth highs.  I have both the 30.1's and the 40.2's - which sound very much alike, as do the 3PSR's.  When driven properly, they sound a lot like the Quad ESL-57's - which are the best.  

While I prefer them driven by the SS Hegel amps (H590 in my case) as demoed by Harbeth at most shows, they can also sound superb with selected great tube amps - which may even give them an even more real, live sound - just depends on the specific set up.  

I hear the Harbeth quality control can be hit or miss. 

The Harbeth do sound nice from those clips but all those clips music all sounded very similar. Is it fair to say Harbeth is not the best choice for an all arounder and perhaps better with classical or slow jazz?

I couldn’t lock myself into a one genre style speaker. But I love the looks, the wood, the sound they deliver with certain styles of music.
