Thank you :D  

Thanks for the reply, I don't hear anything wrong. I'll try alternating the fiio enabled and disabled and see what I can notice.  

I have a pair of Sennheiser HD 598s, and a Fiio E7.   A lot of people said they noticed a HUGE difference when they got a Fiio E7. To be honest, I didn't notice much difference at all. I think the amp works fine, since when I change the bass booster, I can hear a difference, but other people...

I know I know, there are lots of reviews on the E7. But I just got mine and I'm pretty excited! :D   Looks: The thing looks really nice, it feels really solid, I love the little OLED screen. It's a little fatter than I expected, but surprisingly light for it's size.    Sound: It's an Amp...

Alright thanks :) I'll go ahead and buy it then

Sadly I can't afford a pair of HD 800s, but I plan on trying them out someday :D

Well, I listen to Metal and Rock, just like you, I own a pair of Sennheiser HD 598s. They are amazing. And my amp hasn't even arrived yet. They lack some bass. But I'm sure my Fiio E7 will fix that once it gets here. So I'd recommend the HD 598s

Well, I'm using my Sennheiser HD 598 with my Computer. I don't have a soundcard. I'm using onboard Realtek ALC 892. Will I notice a big difference in Sound Quality if I get the Fiio E7? Will I notice any difference a all?  

That would be nice but I would have shipping problems and I prefer not to use used products. I will go for the Xonar DX and pair it with my Fiio E7 Amp Only. If I don't find a DX in my country what alternatives should I consider? I've heard a lot of things about the HT Omega Striker. What do you...

The Xonar DX/D1 sounds good. I have a Fiio E7 on the way, Can I use it amp only with the Card?

If the Sennheiser HD598s are out of your budget try the Audio Technica ATH  M50. If it's still out of your budget, there are some 70$ Grados everybody is talking about that are excellent for the price. EDIT: I just found out your budget is around 400$. I would highly recommend the HD 598s...

-Sennheiser HD 598s -Onboard Sound.   I have 120$ that I can spend on a sound card. Here are my preferences. Music>Guitar Recording>Games.   Music: I listen to metal mostly. Guitar Recording: I use Guitar Rig 5 to record music, sound is horrible recording with onboard sound...

The HD598s have an amazing soundstage.

I'd recommend the Sennheiser HD 598s.

What HP?
