I'm from Hong Kong, new here (been a lurker for a few years). So please forgive my stupid question.
I'm currently using Iphone 5 and a iPod Classic 160G as my main portable source.
Westone 4R, Shure SE535 and AKG 495NC as my listening gear.
Most of my music are ripped in lame mp3 -0 variable bitrate and Apple 256kps AAC file.
I want to upgrade but struggling if I should go with a better DAP or a Amp to use with my iPhone and iPod.
1. Does iBasso HDP R10 is a better choice than adding a Amp like Sony PHA-1?
2. I know my AKG 495NC already have a built in amp, does adding a portable amp will ruin the sound (double ampping? )
3. How about upgrade the ear phone to something like AKG K3003i?
my main question is, which route will give me more noticiable feeling of upgrade?
Thanks a lot for any advise in advance.
