hi there...would be for my sony z1r cans or flc 8s iems..maybe senn hd650 (if i keep them)
Switch the role on the nexus 5 + mojo/ipod brick to a V20 and you shall get the simplicity and the convenience of having the V20 as your daily quality source of audiophile on the go , without the hassle , troublesome of bringing a thick stack on the move , just a piece of extra spare battery is enough for the day .
But having said that , first thing first you got to find out , experience it , whether or not the V20 types of audiophile standards meets your expectations with your iem / headphones .
In my case , my ultimate objective is having a stand alone set-up of just 1 device 1 Iem which is capable for all occasions , currently my primary usage for the V20 is reserve strictly as my daily dose of portable music on the go , for home use I enjoy more on desktop with the creative labs sound blaster E5 which I purchased initially to use it as OTG with the HTC one .
With the current V20 enormous amount of output power at high impedance mode to powered my beloved asg2.5 daily on the move , apparently I don't need having extras , for now .
