Ok...here is my dilema. I have narrowed my choice of receivers to three...the Marantz 7300, the Yamaha 1300, or the Integra 6.3. I am leaning towards the Marantz due to the fact that it has a DAC for each of its channels...whereas the Yamaha has just one and the Integra has one for the left and right channels. I will be using the system for home theater and 2 channel audio listening. My speaker choice presents another dilema. Should I go with the BW CDM 9nt (2300), the Paradigm Studio 100s (1900 dollars), or the Boston Acoustics RM-90s (2000 dollars)? I am just considering going with the CDM 1nt (bookshelf speaker, 500 dollars a piece) and putting the extra money into the sub. Is this a wise choice? I would greatly appreciate any advice to help a newbie like myself out. This system will be used in a fairly large room measuring 14 ft wide by 28 ft deep.
