On another thread, i mentioned that I was interested in a pair of Vienna Acoustics Mozart Grands. I currently am running a HK 445 and was told that I might need to upgrade my equipment to run these speakers. I believe they meant to get an amp/preamp however outside of the receiver and speaker world I am a novice. I was recently looking at the NAD C272, would this amp be enough? Would I be amp to us these speakers with a better receiver say from NAD or Rotel? Also if I got the amp would I be able to us the pre-outs on the HK to connect to the amp to power the Mozarts? Would the amp improve sound quality with the HK or would it be best to get and amp/pre-amp set up?
