Hi oakleaf.
Thanks for trusting my ears.
If you are an imaging junkie, you are in for a real treat. The $1500 system coupled to the Epiphony's will be right up your alley. The Epiphony's do some really cool 'audiophile' things, imaging being right at the top of the list.
When you first plug in the system, plan on it being a bit closed and constrained sounding. Don't panic, it definately opens up after you give it plenty of play time.
Be sure to give the entire system ample break in time. The transformer based pre will probably take the longest to open up. I'd suggest that you take an old CD player (or DVD player), pop in a CD and hit repeat. Let it play 24/7 for a week or two at a moderate volume (read=not low). Granted, thats alot of hours but at the end of it, the system should be nice and 'open' sounding.
Be sure that you use a nice, 'dead' sounding pair of speaker stands for the Epiphony's. If you don't, the stands will tend to embellish the bass and mid-bass making them sound a bit muddy. If you don't have any yet (and you are handy), my Stubby design over at TNT-Audio.com is a quick, easy and inexpensive stand that sounds way better than it should.
When it comes to placing the Epiphony's in your room, don't be afraid to toe them all the way in where they are literally pointing right at your ears. Use a laser pointer to point them right where your head is in your listening seat. If that is too much detail for you, start slowly toeing them out (say) a foot at a time until you find your sweet spot.
After you live with them for a while, PM me or post something down on the GAS Circle (to get my attention), I've got a really easy tweak that can tame some of the harsh treble (baffle diffraction actually) that you get with rock (and other) music. No soldering required, just a pair of scissors and an exacto knife.
Enjoy!
Oh, and welcome to the Audio Circles!
