I know of a guy who has a speaker system consisting of the following:

3-M&K 750 THX Select (L,R,C)

2-M&K 55 (surrounds)

He wants $1000 for the set, is this a good value?? I've read that the 750's are rated at 4 ohms and I have an Onkyo 474 receiver (approx 4 years old, 55 watts/ch), would these speakers sound poorly with my current receiver??
