2 days in with my ZX2 , i think my dx90 will be hitting the FS threads
i also think that it is still in the burn-in period (although 4 months old when i bought it) as the sound seems to be constantly improving
only glitch so far is that i can't seem to make my artwork (cover) appear in the music screen , but i guess i can live with just the great sound quality
i also tried my arrow 4G amp, but i think it collapses the vast ZX2 soundstage and also diminishes the unique signature of the ZX2 (i may be mistaken here though , sotake this with a grain of salt)
only problem i see , i will need (as a 'spoil yourself' gesture) to save some money and buy another TOTL iem to copliment my K3003
i am eyeing JHA angie and Rhapsodio Solar , but these are still just preliminary thoughts as i am 1000$ away from both iems
nice job , SONY - you are finally back among the top dogs
ps : regarding the battery , what is the best way in keeping the battery at a better condition ? is there a recommended charge cycle - ie let it fall to say 20% and then charge it all the way back to 100% ?
or simply charge it whenever you feel like cause it makes no difference ?
