I have a fully active AV51 system and the difference is truly startling from passive. I mean night and day difference. Have you considered trading or selling the two 2250's and getting two 5125's. Then you could drive each speaker fully active with a single 5125 and realize the full potential of the speakers.
Linn Akurate spks, is Aktiv an improvement?
I have a pair of Akurate 242's that I just got earlier this year as part of a complete Linn system. They are bi-amped passively with two 2250 amps. They can be partially Aktiv on the two bass units to extend the bottom from 49hz to 40hz. I'm wondering if the improvement is subtle or dramatic. For what it costs for another amp & the cards, I would be halfway toward the Klimax preamp! Anyone has any experience with "going Aktiv"?
