Most impressive small footprint speaker

Monitor Audio Studio,
and Proac Loudspeakers are very dynamic as well as musical as in natural sounding. Excellent value per dollar I own both after a Lot of comparison testing  .

Harbeth P3ESR – outstanding.

I recently picked up a used pair of Spendor S3/5's. In my small 13x9 listening room they are absolutely addictive. They disappear,throw a wonderful 3D soundstage. Way better bass than I would have ever thought reading their specs. 

 It is whatever sounds good to your ears with you system. Bang for the buck....Harbeth 30.1.

WaveTouch Audio Grand Teton or Antero - the equal of the best out there at a bargain price.

Proac Response D2 - truly magical / majestic / holographic sound with the right tube amplifier (e.g. Line Magnetic 518ia, etc.).

Legacy Audio Calibre - phenomenal resolution, sound quality and soundstage.

Gamut RS3i - as good as it gets... but... at a price.

Any of these when coupled with the right electronics will equal or beat any of those offered by AudioTroy
