Trying to decide if I want to upgrade M60's V3. I should have probably purchased the M80's in the first place! Now I have the amps to push the larger speakers worried about the 4ohm issue at the time. I would like to sell my m60's V3 which I purchased in the outlet store any ideas. Will it be worth my effort to go to the M80's or m100's big price increase over the m80's? Trying to get the most for dollar value. Thanks Greg
