I need help choosing the right amplifier for my 2 channel System. I have a NAD C427 tunner,NAD C326BEE Integrated,MARANTZ CD6005,Peachtree
DAC ITx and Adcom GFA 5300 amp and Dynaudio DM 2/7 speakers. I am using the Adcom because output 125 watts per channel at 4 ohms but I think I need more power because the base is weak. Do you think the NAD C275 will be better than Adcom?

I don't know what you expect in terms of bass, but those speakers are 3db down at 50 Hz, so the bass output of the speakers is inherently limited. You will get very little bass out of those speakers with any amplifier no matter how powerful.

More power is not going to get more bass out of those speakers. You have plenty of power now.

You should put $800 into an NHT B12D subwoofer, and you will have all the bass you could want.

Either that, or get some floorstanding speakers that are rated to go down to 35 Hz or 40 Hz, such as the Dynaudio X36 or the Focal 836V.
