Hi guys Currently using Sound Blaster 2 ZS Platinum Seinheiser PC150 Logitech Z5500's Looking to get better quality sound out of my system mainly for earphone use in the evenings, my budget is quite high so that's not so important(up to £650). I listen to roughly 3-4 hrs of music per night on earphones, so comfort and good build quality also matter alot. I was thinking the new PC650's looked pretty smart and seem to be getting good reviews allround for music. Soundcard, I have been told mine is dated, I would like something that has optical out for the convenience of plugging in the Z5500's straight in. Also something that can potentially boost the quality of the sound. Thinking of a none-creative card due to the driver issues i had with this card. I have been told also that a new earphone cable can increase the quality. As for the earphone amp, any idea of how good these things are and are they worth it? All suggestions and advice are welcome, please help me out Thanks.
