I have been reading posts about amp for Westone 4, still haven't came out with a conclusion.
My source will be iPhone 3GS + Fiio L9 Line Out > Amp
I want smooth mids and highs, good clarity and detailing. Bass as long as it's tight, should be fine. Doesn't strink the soundstage.
I have been eyeing on
iBasso D2+ Boa
Practical Devices XM4
anything else I should be considering? Please help.
