I have never bought near-field speakers, so I may be confused, but I do not think that this is the right situation for them. Would near-field speakers, whose name implies speakers positioned close to the listener be appropraite for an office which is a medium/large room. The speakers will sit 10'+ for me.
Regardless, my amp is set (I love it), so switching to a new amp or a completely new NHT system is not an option.
