hey guys, im new here, i just ordered a pair of beyerdynamic DT770 pro 250 ohm headphones, once i got it, i found out an amplifier wasn't an option, it is crucial for these cans... so i was going to buy the E6s but i heard such good reviews on the E11 amp about the rich warm sound, and adds a punchy bass, so i ordered it, it arrived today and i found out its a portable amp, and i read on an E11 review that if you use these on a desktop (which is where i do all my listening... for now) that the battery will die in no time. is this true? can i still use these on a desktop? so i thought about getting the e10 or e7, but on countless reviews i hear that the e11s will blow them out of the water in sound quality:( what should i do guys, should i keep the e11s?or will they not work good with a desktop? which is where i do the the majority of my listening. should i go with e10 or e7? i want a warm, rich, bassy amp with a nice sound stage. my budget is 100$, the amp doesnt have to be a fiio
PS:im really new to all this.
i listen to some zeppelin, pink floyd, french electronic music(nightcall) and some rap...
