Thanks for the link- one of the best headphone comparison articles I have read, although I thought the M-100 would fare better. The "winner", M4U1, It is an excellent headphone, but I still prefer the M-100. The bass of the M-100 in particular is superior. Both have compararable mids. Highs do extend further on the M4U1. Style, portability and comfort (with XL pads) also go to the M-100.
The only headphone of the group I am not familiar with is the B&W P7. Based on the description, it may give the M-100 a run for its money, but it is also $100 more.
Welcome, yeah one of the better reviews I've read too. Lots of effort into collating the thoughts of different reviewers. I currently own the Momentums and M100's but will admit I am extremely curious about the P7's. I've never heard the cans that they classed as the winning headphone and based on their comparisons, they may not be my cup of tea if they are flatter than the Momentums. To me the perfect headphone would be the beautiful instrument separation and mids of the Momentum's with a marginally brighter top end and bigger soundstage, with the bass quality and speed of the M100's along with their portability and robust build. There is a possibility the P7's may be just that based on what I am reading, except I would say they are as delicate as the Momentums.
