I'm sorry but I just can't agree with that. Just got myself an Fiio E7/E9 combo for Sennheiser HD 598 and....... I'M HUGELY DISAPPOINTED!!!.
It's just rubbish, I was listening to sennheisers for about 6 months just with my laptop ( Dell E4310 ) and I was/still am in love with them, but as I read all the hi-fi forums I was convinced that i should get myself somekinde of amplifter. So I went for that combo and it just .S^&(*# :)
Sorry about that but the stage is just unbelievably small compared to headphones and laptop fix. Obviously they play a lot quieter but i just don't care about that
Got no words for it.
But hey, at the end of the day, you just have to listen to it by yourself. It's just my opinion and I will keep on looking for right amplifter for my ears...
i really liked the benalli ha540 with them. it is 224 on ebay. it is a tube amp as well, i am personally not a fan of ss amps, at least with these cans.
