I know this is a tired topic. I'm not trying to open up a can of worms or anything like that so please do not debate as to which horn is more sensative. That is the least of my concern as I've already heard that there is no significant difference between the two. No difference worth mentioning at least. My question is, is there any other difference between these 2 platforms? Does one have better ramp up or laser detection? Does the M4 platform have a redesigned speaker? I have a vector 955 with the chrome top with the s7 platform and the speaker sounds kind of distorted and I was thinking of trading it in for an M4 platform 955. Is that a good idea?
