we've been testing about 10 different pairs of speakers before deciding and stumbled upon the SA Mantra 60 by accident. Our really patient hifi dealer had a last pair out of his showroom and, after listening to PMC, Neat, Dynaudio, B&W, Elac etc., they literally blew us away w. their quickness, sound and general attitude.
We tested all the speakers w. the same set of albums ranging from Jazz (Herbie Hancock) through Electronica (Massive Attack, Propeller Heads) to Hard Rock / Metal (Rage Against The Machine). The Mantra 60 did them all really really well without sounding "stressed". Given the broad range of music styles they responded amazingly. Only one competitor (in the same price range) came close or even took the lead in the bass section (KEF). However they were dismissed due to their size and space requirement. We chose design over deep base.
This was about 4 years ago....and since then we enjoy them whenever we can. No matter if Reggae, Rock, Classical, Electronical.....all sounds great as long as the source is of acceptable quality of course. We have them paired with our NAD C326bee which is a great fit....although they could for sure take on a more powerful amp.
All in all very happy...and maybe one day we'll add a sub to get to the deepest ranges.
