High value, giant killer speakers?

What speakers have you heard at any price did you find are fairly priced or a great deal and competed with offerings much more expensive (2x, 3x, 4x etc)? 
Absolutely thrilled with the performance of my Tekton Double impact monitors, giant killers for sure
Absolutely without a doubt the new Sonus faber Sonetto 5's. I've owned Focals, B&W  702's and 705's (originals) and Sonus faber Venere 2.5's. For $4,999.00, these speakers far outperform their cost, and compare very favorably to others at twice the price or more. Designed and built in Italy with new woofer design and trickle-down tweeter design, the Sonetto's sing beautifully. Imaging, detail, separation, and easy placement are strong qualities. And their look speaks for itself.
I very recently heard the AudioSolutions Figuro M speakers. From Italy.

Not exactly cheap at $7500, but they sounded like they could compete with speakers at double the money.

Not to mention their finish looked like speakers costing a lot more.
I believe they’re from Lithuania.

Several reviews out there, including this one:

Pity that there only seem to be four dealers at the moment in the USA
