guys, i am going to go separate route sometime next year. so i am doing a little shopping around now. a shop owner demoed his system yesterday and i was blown away. the sound was really crisp and powerful with smooth and airy highs. the sub was really powerful as well. he had sherbourne pt7000 as processor a meridian ( forgot the type ) amplifier an m&k subwoofer with 2 12 inch woofer ( perhaps an mx 5000 m? i forgot ) but they are sooo damn expensive! now i have tons of questions. my new room is 2.8 meter in height, around 4.5 meter wide, 11 meter long. there will be treatment installed on the wall. i will be using monitor audio gold reference series all around. my questions : - what is the difference between using a receiver and using a processor as a pre-amp? - can i just use my old denon avr2802 to produce acceptable sound quality? - i want 7.1 setup, but can i just use a 5 channel amp and let the receiver power the rest of the 2 back channel? what happened if i cranked up the system?...will these 2 channels / speakers be damaged because there is not enough juice to drive them? - any recommendation on a nice processor / a nice receiver that can be used as pre-amp? - any recommendation on a 7 channel amplifier ( 200 watt per channel ) around 2500 dollar? ( i am considering sherbourne 7/2100a ) thank you.
