It's hard to quantify how much improvement you will get in sound quality by pairing the HD600 with a better headphone amplifier. The only way to know is to listen and compare with your existing setup :-)
Based on my experience with the HD600, if you pair it with a modest amplifier (like for example a FiiO E17) the HD600 tends to sounds thin or flat in the treble, and the bass sounds a bit slow. Turning up the volume will still make it sound loud of course, but you will not get better sound quality.
What I suggest is bring your HD600 + iTouch to the headphone shop in Shangrila and try out other headphone amps so you can hear the difference. Yung maganda sa HD600 is it scales up in sound quality when paired with better amps. So yung limitation is your ability to hear better details in the sound and how much money you can spend on the amp :-)
Thank you for that friendly and informative response. Pero sir kung tatanongin ko kayo, sa personal experience niyo if you have the HD600, gano kalaki improvement niya with an amp? Will you definitely buy an amp for the HD600? Ako kasi impressed nako with the HD600, no wonder kasi puro midfi lang hps ko. None of my hps are able to produce that beautiful sound - perfectly balanced and natural sounding. They all sound colored to me now and unnatural. Kaya nag wonder ako kung magimprove pa siya considering how good it already is in my experience. But since they do improve, I guess I just take the risk and go for it hehe...
Did you have any headphone amplifier in mind?
Mga nababasa ko sir ok daw synergy with Darkvoice 336se? How about solid states sir? Any suggestions sir para masala ko na yung choices hehe...
