Advice on NuForce Reference 9 V3


I'm thinking about replacing my Butler TDB 2250 amplifier with a pair of NuForce Reference 9 V3 monoblocks. I'm running with it a pair of Dali Helicon 800 speakers; a Modwright SWL 9.0 linestage preamp; and a Transporter.

Just curious if anyone has any input on pairing the NuForce Ref9 V3 monoblocks with this kind of setup, or any opinions on it vs. the Butler.

Thanks...

What do you find wrong with the Butler amp? I have thought about doing the reverse. I have the older Ref 8's for HT and wanted to try the Butler amp with my Sonus Faber's.
