My advice is, sell your amps and use the money to buy more content to enjoy!
hello Descartes,
you have passive speakers... you have the weird idea to buy some actives... ...
well... my advice is : follow the Inner Space's advice
=> jump into the active world, and you will never come back to passive !
The 1st step is to go & listen. Actives are like passives, each brand / model has its "sound". Then, you'll like more this one than this other one... the ears will choose !
2nd step, after testing at home 2 or 3 actives (front & center), you'll realize that you entered into a brand new wondelful world, and ASAP you'll look for swaping the other passive speakers to get only actives ! Because it's so much "better" (and cheaper & less cables & smaller electricity bill & less boxes into the room, and many others advantages
).
Why do you have in mind the biggest items from Neumann & Genelec ?
listening position @ 12feet... that's not "far away"...
and why not looking at Dynaudio Core / Adams / Focal trio11 / PSI A-23 or 25 / ... ?? theses are nice products too. The "active world" is not limited to Neumann & Genelec !
