A good rule of thumb is around 4' out from the front wall and then get the ribbons pointed right at your ears.
I messed around with mine a few weeks ago and the sound went from it's okay to WOW!

I Have a Parasound Halo, but upgraded to Odyssey Kismet /Stratos, you may need to have a higher current amp(60 amps ) you may find the Halo wanting in terms of power for the 3.7i, If I choose to upgrade to 3.7i I would probably go for two mono amps.
