Well I finally have my choices, (if you saw my other thread)
iPod Classic 7th generation
Fiio L9 LOD
Maverick Audio TubeMagic D1
Senns HD650 or HD600??
The HD650 do well on soft rock. With more aggressive genres go for something else.
I don't know if Hendrix and Ledzep are brutal enough, but I happen to like them through a HD650. I mean they sure as hell ain't soft because I'm not when I listen to them!
This is how I feel as regards to the HD650's being "laidback". Forward presentation, metaphorically speaking, would be like someone shoving you lightly. It is somewhat forced upon you. I feel like in the case of the HD650s, it's like a large man just standing 2 inches from you breathing into your face. Let there be no doubt...I am acutely aware of his presence LOL.
