I already own the Fii0 X1,and I am very happy with it.
My main IEM's are the Sennheiser IE800 ,& the Vsonic GR-07,Dunu Titan's-1.,& the ATH R-70x headphone.
Can someone suggest ,a few other options, for an upgrade?
I' do NOT need DSD,.
What I am looking for is the highest sound quality,I can get,with a portable unit.,size is not really an issue either,if its around the same size as the X-1
Price limit ,will be $500.00
90% of my files are AIFF,so,need a lot of...
