Electroman, I'm not familiar with the conversion from cu. feet to sq. feet. What's the sq. footage of your room? Am I way off thinking it may be about 30' x 15'? (My sq ft HT is 23'x13' with ceiling of roughly 8'. Multiply them together and I get 2,392 - is that right for cubic feet?)
Obviously, I'm not expert; would appreciate a post clarifying.
Anyway, if my calculations are correct/ballpark, then this room Electrostatman is discussing is not monstrously large, and Speakers such as Eminent Technology's, Magnepans, or Vandersteens could certainly work. Especially if supported by twin subs.
If I'm way off on the measurements, I'd have to reconsider.
Electro. maybe you would like to determine how much personal effort you want to put into assembing your system. $30k is a big chunk to spend on components assembled from Agon recommendations.
You obviously have deep enough pockets to afford spending a few dollars on consulting. Seek out the highest quality audio salon near you (or two). Be very up front; tell them you're paying them for an hour or two of their time for expertise. Not for their equipment. Ask them to put together the best possible system for the $, using both items they sell as well as ones they don't.
If they don't want to play that game, walk away.
But, if they are willing to consult and sell a combo of their pieces as well as other recommended components, you could end up with a significantly better system than finding things on your own. They may give you insights you'd never learn on your own.
Again, if it's made clear you're paying them for consulting, then you don't need to feel obligated to buy their systems. They should know that up front. If their equipment/recommendations has enough merit, then they'll profit from it.
I paid $70/hour for a HT consultant from a high end independent audio shop when I built my HT. VERY worth the money spent. I would suggest two consultations with different shops. Amazing what you can learn from competitors.
I also recommend a subscription to "Home Theater Builder" magazine, if you plan on rehabing the room. Even if not, it's a terrific read to give you ideas on what kind of equipment you could pursue. You can obtain back issues. When spending that kind of $, you want to get the room "tuned" well too.
The difficulty with all this is that it seems you won't get to hear the final system until it's up and running in your room. To do that, you'd likely have to support the local audio shop by purchasing from them, and they could loan components to you to demo. If you want to go it on your own, spend lots of time researching the components and thinking about compatability/integration, i.e. will all components be able to be controlled by universal remote.
If you get some esoteric equipment that doesn't have remotes, etc. you may be frustrated at having to mess with switches all the time, etc. Also, if this will be used by family members, you need to keep it simple enough operationally, or it'll collect dust.
One last thought; become intimately familiar with audioreview.com an excellent source to weigh in on used equipment being considered.
