Nuforce Ref 18. Anyone listenned yet?


Hello,
I am in searching to upgrade my amps (Nuforce Ref9SEV3). Probably a pair of Nuforce Ref18. Just curious if anyone had a chance to hook them up in your system yet. How do you compare the Ref18 to the older Ref9SEV3? Your help and inputs are greatly appreciated!
Have a good one,
LN
