Er, you're getting this slightly wrong. You're taking the physical size against the capability of the headphone design, the source and the recording quality
no sir - the concept of hi fidelity is that it should sound as close to the original as it can and this would include scale and size (it has to because thats why high end hi-fi exists). The absolute best hi-fi system i have heard actually sounded so holographic that you FELT as if you could stand up and walk amongst the performers and possibly shake hands with all of them and it was a combination of equipment and room size as well as room treatment in the dedicated room that made all the difference
Headphones does not get you to anywhere close to this effect and granted if you listen to wharfedale 9.1's then possibly you have never experienced what im talking about but saying that headphones beats any system you have heard is a gross exaggeration. The owner of that system that i listened to also owns a pair of sennheiser HD800's which are respectable headphones i would assume as well as having those connected to a headphone amplifier and we played back the same recordings with the same source as we used for listening to the speakers and separates combination and the effect was nowhere as near convincing or even close to having the same amount of fidelity
so im sure it all depends on your experience of hi-fi equipment and im happy for you if your headphones sound good on the train but to say it beats all hi-fi's out there is ridiculous and IMHO that is the actual trolling because im not the one who is trolling
i have also noticed a trend that whenever the same poster encounters anyone with an opinion different to his then those posters are accused of trolling ... why do i sense a pattern from him AND one more thing even though i dont post much it doesnt mean im a newbie on the forum (hint look at my join date) and it also does not mean that im a newbie to hi-fidelity equipment
