I'm a big audiophile but I really don't enjoy my gear and wish for a lot better.
I have tons of CD's and a 3GB FLAC music library in my computer.
As for now, my gear is pretty simple - I have onboard Sound Card. My motherboard is Gigabyte Z77-D3H.
And I have nice headphones which are the Sennheiser HD555s.
Also I got a simple Denon amp which actually used for some kind of home theater.
What I do is I plug my PC to the amp via optical cable (SPDIF) and plug the headphones to the amp (which has 6.3mm output).
But I really believe I can get much better performance with completely different gear and devices.
The main problem is my knowledge. Beside the fact I'm really love music and I'm a big audiophile, I really almost don't know nothing about music equipment and this is why I really NEED your help deciding when I should purchase.
My budget for everything I need is 600$.
I was actually thinking of getting a new external sound card, the Asus Xonar STX, and buy a new headphones, the Sennheiser HD650.
But as I said before, I really don't know much to know if this decision is even good.
So I'd really appreciate any help.
Thanks in advance!
