[ARSCLIST] Balancing Amps?

[Andy Kolovos <akolovos@xxxxxxxxxxxxxxxxxxxxxxxxx>]

Folks,

After a long (and hopefully not foolhardy) struggle our new studio/lab 
space is nearing completion.  Now that I'm finally ready to get down to 
setting up my junk and starting work again, I need some advice from my 
fellow ARSC Members.

In addition to putting in a new space, we've also made several big 
technical upgrades around here, and one of the major ones was our jump 
from a DAL CardDeluxe to an Apogee Rosetta 800.  This stated, I'm in the 
market for a balancing amp to connect my Dragons to the Apogee.  I've 
looked at some, been directed to some and now I want to see what people 
in our field are actually using.  Can anyone share the gear they've been 
employing?

The gear I've been investigating is all below.  We need between 4 and 6 
channels total, but I don't mind achieving this through the use of 
several two channel boxes--nor do I mind spending $125-$200 a channel 
for clean pass through.  I also would greatly appreciate opinions on 
passive vs active systems for this application.

Thanks in advance!
