hello all, i am using nuforce ref-9SEs, had the standard ref-9s and upgraded, the upgrade brought a already fine amp to a much better place, a more refined, detailed, and musical amp, this is the last excerpts from Edgar Kramer 6 moons, ''I've owned/auditioned/assessed/compared scores of excellent amplifiers using all manner of technology and circuitry. I consider the NuForce Reference 9 Special Edition amplifiers to be amongst a select small group of the very best amplifiers I've heard. In fact, the SEs better most of these elitists in the areas of resolution, dynamics, bass power and frequency-wide detail.
As the seasons turn and the old leaves wither away, the promise of imminent new life and rebirth swell in our universal consciousness. In a life-assimilating fashion, the NuForce Reference 9 Special Edition mono amplifiers have inspired a new cognition of what the future of amplification will be''
there are other reviews by pros not one was negative for musical performance of these fine amps, im not a pro and can hear it, yes its worth the extra money for SE, in my system which for me is as musical as any i have had the pleasure to hear, i am going to comment on the fm rf interference with nuforce, i dont have a tuner in my system and havent had one sense my marantz model 20 years ago, i do have my cable box as a input on my preamp, and when i am messing around the house, and not trying to get into the music, just listening in the back ground, the music channels on my cable box come in handy, when the time comes for sit down into the music time, fm or cable boxes just wont do, for me its a analog front end, you have to have your system synergy right on, to be able to listen for hours on end with out fatigue, and drifting from the music, with my nuforce equipment in concert with the rest of my system i have that, music realism almost like being there, if you can get a chance give the nuforce gear a listen, great musical days for all, mike
