Choice: Avantgarde Duo Omega or JBL K2 s9800

Am now able to get both of these speakers at abt the same price albeit both in demo condition.

Am now using a pair of Vandersteen 2CE Sig2 and Harbeth M30 and really wanting to try the other end of the spectrum. Heard the Quad ESL which may not be the ones for me where now decide to go the way of the horns.

A/B audition is not possible where i am attracted to JBL K2 s9800 primarily becos its (correct me if i m wrong) a mix of HORN and monitor (best of both worlds?) and also being the 2nd highest in teh line of JBL. Wld tis not make a more sound/safe investment? Same time not really sure of its dynamics as compared to the avantgarde ....

i want to stay with my BAT pre/power (vk32/vk55) ....

any comments welcomed!!!
