eightmanvt- If the VT in your name stands for Vermont- I live in Burlington, VT and own the m-60's. After you receive the 80's, I will be glad to let you do a comparison.
However, I do not have HT, just a two-channel music system,
but it might help you. Let me know.
The m-60's are fantastic- you wont go wrong either way.
