If i felt the reviewer wasn't on point I would call it out but funny enough I got my M80v4's in yesterday to replace my m80ti's. I happen to have the Led Zeppelin remasters CD's in my possession so I listened to the two songs the reviewer used and I have to say he's right! I did not do a full compare of both sets but to me the m80 v4's seem just as detailed as the m80ti but smoother is the best way to describe it. I'm very happy with the upgrade. I'm currently running them on the Marantz SR7010.
