I find it pretty sad how these threads work. You guys are saying that it's the best portable headphone ever, and anyone saying anything below that gets flamed. I fully believe there's a dozen or so users who think the same as I do, or think less of the KEF, but can't be bothered to share their views because of all the compulsory arguing that will follow. I've done the same with other headphones, remaining tight lipped about a few 'headfi' favourite headphones that I own now where I think they sound rubbish, which won't go down well on these forums. Better to say nothing.
It is public record I had the good fortune to weekend home demo the Momentum and KEF M500, had no pressure to buy and made an independent purchase decision at the end of it. I have zero need to justify any purchase as I maximise every opportunity to demo prior to buying, as I would advise any person.
All of the above is irrelevant. My issue with your post was the inference. You have to appreciate such a statement has a very powerful and deliberate inference, even if it is unintentional on your part. To publicly correct: there are a lot more than merely two dealers of KEF M500 in London. Heck pretty much every independent hi-fi dealer has them in nationwide.
The opinion of two dealers out of many that prefer another headphone? Fine. The opinion of the "only two dealers in London" that prefer another headphone? The second is not a factually correct statement as there are tens of dealers in London. There is a huge contextual difference between the two statements. Most people on Head-Fi do not have the opportunity to demo. Please take care with your posts. I would have said the same thing if your post was about the Momentum, which I think is a very credible headphone.
