Hi guys,
Well...first of all, sorry about bad english.
I've been thinking A LOT about replacing my old pendrive style Sony NW-E015F for another new generation Sony Walkman. I find my E015F to have a really, really nice SQ for its size, and i'm wondering if I would notice any serious improvement in sound quality if a I bought a Sony A818. And what kind of improvement would the A818 provide ?, loudness ?, details ?. I'd like to listen more details in my songs, since I've heard a lot of the them in my computer through my MDR-EX71s and there's a whole other level of detail.
I know that the headphones plays a big roll in music's SQ, so here's my other question: the EX71s are really good, but I'm tempted to buy a new pair of on-ear Sennheiser's (PX200). ¿would that change make an noticeable difference?.
That's it, I hope u guys can guide me through my personal audio update

, because I really wanna spend my money well.
Peace.
