Hi I need some help, I am just setting up my first home cinema system and i have mission 702e (front) mission 75c (centre) and mission 700 (rear). I will be using it for both films and music. I like my music crystal clear and not too bassy or trebly. I can get a good 2nd hand deal on either of the following 3 receivers - denon avr 1804 marantz sr5200 yamaha htr-5540rds Which do you recommend and why? Thankyou.
