Amp play a low volumes?

Thank you guys for all of the replies. I will probably be getting the equipment fairly soon, and it should be fun to hear a good system in my house for once.

As a follow up to my comments above, I thought it might be useful to report that I just took delivery of a NAD C350 yesterday. My initial reaction is very favorable and it has not been burned in. The amp plays fine at high and low volume and does not shut down at low volume. It is a very synergistic match for B&W DM602s2's and has thus far outperformed much more expensive equipment with these speakers. I still suggest you leave the soft clipping button in the off position.

Actually, there has been a more exhaustive study conducted some time after the Fletcher-Munson materials were presented. It supposedly delves deeper and with more accuracy as to exactly what takes place in our ears in terms of volume vs frequency response. Can't recall the name of it, so someone help me out on this one if you know.

Marakanetz, please expound upon your statement about speakers adjusted for the same listening level sounding "quieter" or "louder" than the other. I think i know where you are coming from / going to with this one, but i'm not sure. Sean

I think that Robinson and Dadson (1956) are responsible for refining the work of Fletcher-Munson (1933). Can we trust these scientists? Lord knows Nyquist is not trusted.

How low(volumewise) can a real trumpet sound? How low can any brass instrument sound(also volumewise)? How low do you listen to a real piano or grand-piano in the room? Did you try to sing along with the singer that you hear from your speaker in unison or a-aapella or voice-duo? I think that how low should a speaker reveal its sounds as close as possible. If you're listening to an orchestra than the orchestra must be reproduced correspondedly proportional in your listening room(certainly there is no ideal reproduction of the recorded music but as close as possible).
