Simple answer to this question........................"NONE!!!"  Be smart.  Always audition before purchasing the most important component in your audio system..........."Speakers."   

I upgraded from monitor audio silver RX6 (and RS6 before that) to GoldenEar Triton Twos, then to the Triton Ones that I currently have. Compared to the RX6s, the Twos opened up the soundstage and added space & detail between all the elements in the music. The Triton Ones upped the ante even more: both can be purchased used for maybe 40% of original cost, and are a HUGE upgrade over the Monitor Audios (which are also very good). Used Twos can be had for $1,300 or so, Ones for another thousand. With good cables, they’ll accurately reproduce every detail in your music source, and could be your forever speakers. I know they’re mine.

+1.

Bought Aerial Acoustic 7t's without hearing them to pair with .operate to high powered solid state amps.  I am one lucky SOB cause that are the best speakers I have ever owned out of about 15 plus pairs.
