why did I know that you would hav zero sense of humour about that comment jeeze man, loosen the hell up!! I love you crusaders; supposedly 'found the light' and have to try to kill everyone elses joy. what do you get out of this process? this convo is against the rules, so i'm not going to discuss you stupid tests. seriously if you honestly feel like this. you really have no reason to be here and that includes home AND portable. i'm curious ho you choose your headphones? do they have an isolation booth at your shops? do you choose based on graphs? seems pretty lifeless to me

However, obviously this forum section isn't primarily, if at all, based on that. It's meant for on-the-go listening. Full sized cans are portable, but they're not really for on-the-go listening. You shouldn't be using them on the bus, or walking around in the street. The first reason being that you're unlikely to be able to hear the subtle differences you detect in your quiet home environment, and the second being that they are too isolating for such a public environment where your safety and the safety of those around you depends on awareness of your surroundings.
I dare you to take the time to do a legitimate abx test (with and without your headphones plugged into all of that) with matched volume and post the results. IE You're not allowed to see what you're listening to, you just have to try and tell which is which by hearing them do their thing.
It's really bad practice to do sighted trials, and even worse to make claims to other people based on them. ABX isn't perfect, of course, but at least it tells you something. All what you've posted tells a reader is that you've spent a lot of money and you personally have decided it sounds better. The reader is left to guess why you think it sounds better, and sadly the most obvious is not because it actually does.

not going there, you really oughto just do your own thing mate, sounds like you have lots of rules that other people must follow. shouldnt use headphones in public environment ...jebus man!! in fact fullsize headphones have far less isolation in general

It's KSC 75s and a totally encased mp3 player or nothing.

I live my life primarily as a kind of shift worker. most of my business is on the other side of the world and therefore in a different time zone. I do most of my listening between 11pm and 4am, the majority of that is downstairs in an under the house workshop with little security, so nothing is set up down there and power plugs are at a premium. my home rig is upstairs and its staying there. I often go for walks to clear my head, grab a coffee or supplies at the 7/11 etc. its pretty quiet....
everyone seems to be avoiding the question, if you cant tell the difference between 2 very different dacs portable (for some reason everyone is focusing on the amp because to people who know nothing of impedance issues its an easier argument when talking low ohm cans) , how do you choose your headphones, your DAP?? totally based on features? how it looks? in that case again you would only need to go to one of any number of other websites that cover the consumer angle, but yet you are here and I can bet the way your dap and headphones sound are at least part of the reason you own it. the rig above can quite easily compete with home rigs of the same value driving any headphone you want, so makes a nice work rig driving the JH13 or HD600 if i'm doing paperwork or something and like I said I carry my bag around with me anyway and i'm not gonna say to myself 'hmmm I think I would be better off not hearing some detail at the moment i'll disconnect my rig so its not such a hassle and reconnect it all again later instead of slinging my bag over my shoulder hitting play on the remote and off I go; which sounds more convenient to you?
and alex raises one of the same points I was making. multidriver low impedance phones are NOT well driven by portable players, there is plenty of science to back this up and yes DBT as well. anythingbutipod did some testing with a scope of sorts as well.
but I suppose you guys will argue the testing conditions or something idiotic like that.
anyway i'm out, not buying into this any longer as I can only see one agenda here. I personally couldnt care less what you guys do in your own time, I suggest you take a similar attitude and go get on with it
