Recommended amplifiers for bi-amping JBL XPL 200

Hello to all.
This is my first time posting in this forum. Would like your opinion on what amps would be good match to bi-amp my JBL XPL 200 speakers using the companion JBL DX-1 electronic crossover. I'm currently using a Harman Kardon PA 2400 for the lows and a Harman Kardon PA 2200 for the highs. Not really happy with the sound and feel that may be able to get a better amps to improve the sound. Was thinking of getting a Harman Kardon citation 7.1 and used in the bridged mode for the lows and maybe another amp like the HK citation 5.1 for the highs. Budget is limited to maybe 2K. Any advice will be greatly appreciated.
Thank you.
Hello Pablor. I stumbled on your message totally by chance. I can't make any suggestion except share with you the setup I had when I owned a pair of XPL-200's. I had 2 second hand first generation Bryston amps, a 4B to drive the lows and a 3B for mids and highs. The sound was just amazing. 
If I may add a little. The XPL-200's (6 ohms) require 200 W RMS minimum with peaks of 800 W. So you can give these puppies a lot of juice. I think your setup comes short of delivering adequate power. If you can afford more powerful amps, go for it. You won't be sorry.
