Fataechak, welcome to the board. That is an extremely hard question to answer. First of all, what are you planning on. Just HT, and what size is the room. Also, do you plan on using separate components, IE processer, and amp, or just a receiver all in one package. Look into the Yamaha, Denon, NAD, Marantz, B&K, and my favorite Rotel. I personally suggest staying away from Onkyo, Sony and Pioneer unless you get their flagship models. I have had Onkyo and Sony and both seemed under powered to me. I have read about others not liking Pioneer.
Both the M60's, and M80's are great speakers, depending on your room size and budget will determine that. The M80's are an easy 4Ohm load and most receivers will do OK with them.
