Scott,
I own and have owned NAD amps, receivers, integrateds but have not owned the 375. They all have driven my Klipsch Heresys, fortes, Quartets, and RF-63's very well. I presently own the Yamaha A-S1000 integrated and could not be more pleased how it drives my Klipsch RB-75 "bookshelf" speakers. Dynamics are free wheeling, soundstage is wide and deep, very punchy and detailed. Now you are talking about the A-S2000 which is the slightly bigger brother Yamaha. I can't say for sure that the Yamaha integrateds(1000 or 2000) will have the dynamics of the NAD 375, but they are the most powerful sounding 90w/ch amps I have ever had the pleasure to own or even listen to.
Bill
