Who has gone fully active? What speakers and preamp did you end up with?

@erik_squires You need at least a 10-1 ratio between the amp and preamp in normal situations

@willywonka - I am familiar with the rule of thumb. I just don’t know how many preamps have an output impedance higher than 1k Ohm. And it is actually just a rule of thumb. 

@daniel25  - Interesting that ATC lists the input impedance at > 10kOhms.  That does seem relatively low.  I'm used to seeing 25k or higher but hopefully it doesn't affect too many tube pres.
