I'm not very kean with technical specifications and have a question for specialists:
I'd like to use a Conrad Johnson preamplifier on my Ref 9V2.
This preamplifier has Gain: 28.5 db, Maximum output: 5.5 vrms and
Phase inverting like most conrad johnson preamplifiers.
Is it a problem with Nuforce amplifiers?
Are there any impedance mismatching if I use four Ref 9V2 for bi-amping (they will share the preamplifier outputs)?
Thanks for your help
