IMO,A&K players for iems to use.
You can't feed your HD650 with AK100ii.HD650 needs much power.My RWAK240 can't ride HD650 without an amp too.
If you want to ride hard headphones like HD650,HD598,HD800 etc, you need an amp.
I kind of figured as much after getting my unit and listening to it. I think I jumped the gun when buying the AK100 II as it doesn't suit what I was trying to accomplish. I'm thinking I should return the unit and use the money for a setup that would more fit my desire to purchase the HD 650. I guess the other question I should ask before making any decision is how much money would I be looking at to amp something like the HD 650 from the AK100 II? Would something like the Schiit Magni 2 Uber work, or do I need to spend more money than that? I like the idea of having a portable player like the AK and would consider keeping it if I can amp it without breaking the bank.
