I admire those Martin Logan ES speakers a lot!
My 2-channel main system is incredible, too (so says everyone who listens for a bit!):
Bi-amped dipolar Carver Amazing Loudspeakers from the 90's standing about 5' 6" tall and about 36" wide at the base, but only about 5" deep, modified with external crossovers and Rane equalizers and 4 tube-like sound solid state amps (with a 575-1200w monoblock Carver Silver 9t amplifier for each speaker's 60" full-range ribbon and a Silver 7t 575-1200w monoblock for each bank of 4 12" woofers), a Sunfire Classic Tube Preamp, a hybrid solid state/tube output CD player (Carver S/DA490t), Carver Sonic Hologram C-9 generator, a BBE Sonic Maximizer circuit, Dual CS 5000 turntable w/ Shure V-15 Type V-MR cartridge, Sony ES DAT deck, Sony ES tuner, Carver SD/A 390t tube output CD carousel, and a TEAC 4-channel reel to reel tape deck.
Set up carefully, adjusted for room acoustics, etc. - these are simply outstanding and will play ANYTHING and any kind of music with lots of "air" around instruments, fantastic sound stage and presence, don't need no subwoofer -- there are 8 12" woofers pumping bass you can feel in your bones when needed, and a 3 dimensional sound spreading way beyond the edges of the actual speakers. The ribbons are incredible and are much like the electrostatics in playback.
I bought 4 back-up woofers and surrounds recently from the speaker manufacturer just in case the foam surrounds or the planar surfaces or the cones ever go -- crossing my fingers that won't happen ever!
I'm a classical music/opera fan, but love club music, jazz, the Beatles, middle-eastern, flamenco, vocals, dance mixes, piano, new age, you name it. And this system puts out like no other I've auditioned. No, it's not been inexpensive, but well worth the costs IMO! One can truly lose himself in the sound and close out the rest of the world for a while.
