Best HT speaker system

All those are nice, but if you want great dynamics and incredible smoothness, go with the Linn AV system, it's amazing. If you've got more money than you know what to do with, the Revel Ultima series if impossible to beat, but the #38,000 price kind of is out of my reach!

I use all clzIIz for front and rears as well as a logos. I appreciate how electrostatics can deliver at low volumes across the sonic spectrum. I have two velodyne subs @ 50 hz for the bottom end. I am using cardas neutral reference speaker cable, a mc1, and a krell kav-500. I have used the apm-1 genesis (2 pairs) with the logos, but found nothing can touch an electrostatic for great fidelity at low volume. The genesis setup is now used for very loud ht and music in my other, less used, room.

i saw and heard several jm lab ht systems at ces. they have a very large selection and their "big" stuff is as impressive as grand utopias on 2-channel. they are beautiful, too. well worth auditioning.

This is a little outside the box but here goes. Pick for yourself your favorite a/v pre/proc with balanced outs to all channels. Then buy as many GENELEC ACTIVE monitors as you want!(this company is based in Finland and have been around for 20 yrs.) As much as i love audiophile speakers driven by great amps, the above setup will pummel all comers. These speakers are of extremely high resolution(in a good way), and they Will Not Bottom out ever! The Genelec model HT 208 is a two way w/ a 1" twtr and 8" mid/woof--they play ~45hz to 22khz. Capable of 120+db without compression for sustained periods of time. Cost is $2300ea. Bear in mind that includes the built in amps. Also active crossovers feeding bandwidth specific amplfiers(120watts per driver!). Add the subs of your choice, spec the right balanced interconnects and you have a HT that is most impressive. Your room is pretty large, so its gonna take some serious gear to pressurize it without blowing up, this scenario will do it for you with ease.

used linn speakers are hard to beat and there are quite a few around...you always have the option of going active with linn cards and amps, too, and that materially improves the already excellent sound

fwiw
