Linn Aktiv Kabers vs Dynaudio Contour S5.4

I've moved my 2channel system to the lower level of my home in an open ended room 20'X 60+'. My Kabers are having a tough time producing exceptable lows, otherwise they're great. Tapped in my HT sub which helped a bit but the sub is too slow for the Kabers. Here's where I'm at:

Linn Karin
Linn Aktiv Tunbox Kaber
3- Lk 100 Amps
8' K-600 Speaker Cable
Linn Interconnets
Activ Linn Kabers

New System:
Cary 303/200 w/ variable output
MCIntosh 402 amp
Dynaudio Contour S5.4
Cardes or Tara interconnects

Lose the kabers and go for the Dynaudios. Oh and by the way, if you are thinking of selling the Kabers - please let me know, I'll take 'em. ;-)
Thanks for the tip. Opted to NOT buy the Dyna's for now. Since you know Linn you know I have to get something clearly better or I won't move.

None in my area!
Sold the entire Linn rig for the Wisdom Adrenaline Speaker system. Time to move up and the Wisdom's were a leap up for my ears. Now it's time for a new front end to run these beasts. Might consider some more Linn gear.
