Hello everyone, I hoping to draw upon all of your experience and expertise and I thank you in advance for your assistance. I am putting together a 5.1 home theater to go with my 65” widescreen Mitsubishi HD TV. I have decided to go with the M&K 750 MKII 5.1 THX Select speaker system. Worth noting is that the front three speakers in that system are 4-ohm. I am now trying to find a receiver that will work well with that speaker system. Further, I do want the THX post processing but do not care if it is select or ultra. Most importantly, my budget will put me in the $800-$1200 range for the receiver. I have done a little homework and found that only a few receivers will meet all my requirements. Dennon doesn’t include THX processing in receivers in my price range or they would be my first choice. I like the pioneer receivers that do have the THX processing but they specifically say do not use with 4-ohm speakers. I know that historically the amps used in Onkyo receivers didn’t work well with 4-ohm speakers but this years models TX-NR900 and TX-SR800 both have menu settings for 4-ohm speakers. I have also noticed that the H/K AVR 8000 has been discounted to the point that if falls into my price range. Thus my two leading choices are the Onkyo TX-NR900 and the H/K AVR 8000 with the H/K AVR 8000 being slightly preferred at the moment. I am wondering if anyone here would have any comments regarding either of these two receivers that would be relevant to my decision. Further I welcome any other suggestions. Thanks PS Regarding the M&K 750 MkII speaker system I am also wondering if you folks think it would be worth upgrading the V-1250 sub to the MX-150 for an extra $350. Thanks!
