I also have the M60s and love the sound and increased imaging from what I was used to (15 year old 3-way towers). I mostly used my system for HT but now I am enjoying music a lot more. Everything is crystal clear and I can hear a lot more detail in the music and its very enjoyable now. Instruments sound like they are right there in the room. They are not really broken in yet but I did experience the break-in period last year with my sub. It did improve after some time so my M60s should even sound better soon......
