Anyone using Nuforce Ref 9 Mono Blocks?

A friend of mine while auditioning the Nuforce 9SE at home, could not hear radio through is Tivoli One because of RFI problems caused by the amp. Reception was better when the NuForce was connected to AC through a shielded Siltech power cord.
RFI is a real issue with this amp.
As to my opinion I enjoyed some aspects of the sound, but I would not buy the amp. NO.

is this RFI probelm limited to nuforce, or does occur to all other switching amp. rowland, channel island...etc

Can't speak for any other brand, but as noted above I do not have any RFI problems with my Bel Canto S300. It is a switching amp and is located about 12" from my tuner. I get both AM & FM just fine.

I am with Mlsstl. My Bel Canto M300s (the monoblock version of the S300) is superb in my system, driving VR-4 JRs. No radio interference, plenty of power, smooth, detailed. Can't compare to the other amps since I haven't auditioned them. And if it matters to you, the reviewers agree.

I have never heard a problem with the 9SE. The 9Se was a major redesign of the original 9s.

I invite anyone interested to come to my place and see for themselves, we are located in Jersey City NJ 3 Miles outside of New York City.

Nu Force 9Se are amazing amplifiers and are more musically involving than the ICE amplifiers.
