hi,
 i would really like to forget about electromagnetic/radio/mojo interferences when commuting.
after pestering some member with PMs (thx everybody) i've got a few leads but i need your help for some more peculiar demands on amps.
 
 
so my perfect amp would:
-give me zero noise from cellphones.
-have the darkest background possible, hiss is my nemesis. (i'm on jh13 and ie80 most of the times)
-under 2ohm output impedance
-would go lower in bass than my actual rsa protector.not louder, just lower.  (i love the sweetness of this amp but i really feel like it cuts the lowest range of frequencies too soon compared to other sources )
-i must pass the 10hours mark with the battery paired to my jh13. else i would get a dx100 and forget about all this (ibasso why u no make bigger battery?).
 
 
i don't use fullsize headphones so i don't really need a monster in gain.
price is not important if i can at last live my life with no audio worries.
 
 
i know i'm asking a lot, i come to you because reading reviews only led me so far. thank for your time.
 
 
 
 
 
you guys are my
