Chess - I am familiar with this type of mono test - back in the late 70's, when I actually was employed full time selling audio equipment, this was how we evaluated speakers under consideration for the store. Those were fun times in audio ... beefy amps, great two channel sound ...

I have a feeling this GTG will be a lot "lighter" than that - but let's see what happens between now and November.

Adrian - I have not heard the Martin Logan subs. They do look interesting. It's likely I will be purchasing a pair of SVS PC-12 Plus subs to compare to a single EP-800.

The PC-12's are $300 less than the outlet price (A Stock) for the EP-800, but a $2180 package vs. a $2480 package seems pretty fair, especially considering the "higher WAF" of the $2480 package.

I might also grab a pair of Prime Towers. Between the M100's, M50's, Martin Logan ESL Hybrids and Prime Towers ... PLUS an EP800 / PC-12 plus pair, there will be plenty to keep me busy having fun.
