Hi. My current stereo system consist of a C320BEE NAD integrated amplifier which is in preamp mode with a Golden Theater amp as this amp provides more power than the C320BEE gives with Triangle Antal ESW speakers. Anyway, I love the NAD sound but the Golden Theater amp has a problem (it shuts up at will) and as I can't repair it and will need to get a new system. I was thinking about the NAD C272/C162 combo, BUT my fear is paying for that combo and realize that this COMBO won't sound as good and lovable as my current systems does. There must be something with the "BEE" component on NAD systems that make the difference. Anyway, I was thinking of this combo: get a NAD C325BEE and use it in preamp mode feeded with a NAD C272. This way, I think, I will have the NAD BEE sound I love but with more clean power that will be provided by the NAD C272. What do you think? What I want is to keep the refinement and musicality of my NAD C320BEE with this new combo. What gives the sound to a system: the preamp or the amp? Any insights will be very much appreciated. Thank you again.
