Hello Outlaw Nation.....I am currently pushing a pair of Paradigm Monitor 9's with a Harman Kardon 3480. Overall I am plesed with the HK's bang for the buck. However,I still think it could be better. Recently I've been considering a preamp to go with my HK. Would I be better off trying the preamp/HK combo,or ditching the HK all together and buying the RR2150?
