Can't think of a better first post than to say I just sold my pair of Beats Studios and have a pair of Sennheiser 558s incoming :)
With that being said, I am a newb to Hi Fi audio (in fact, I don't think the 558s even qualify, do they?) and have a few questions:
1. Will I see a big difference with an amp for the 558? I mainly use my laptop with it's onboard soundcard and an iPod Touch 4G. I'm looking at an Fiio E7.
2. Without an amp, will the above two devices drive the 558 just fine?
3. Will the DAC from the E7 cure my ground loop problem? My laptop's 3.5mm jack hisses and buzzes like crazy when the charger is plugged in.
4. How much can EQing affect a pair of headphones? Say I have two similar pair, both of similar specs but different freq response, is it possible to EQ one pair into the other (or close)? Take the beats for example, if you attempt to flatten them (lower lows and highs, boost mids), would they even sound remotely close to a pair of headphones that was flat to begin with?
On a side note, I got the Beats for ~$100 and felt that they weren't terrible. I didn't sell them because of the sound quality (especially considering the price I paid), it's just that the noise canceling hiss was pretty annoying and my pair was incredibly tight. The main draw of them were their looks and the fact that their bass was very powerful, even if they are "muddy", whatever that means, and in that respect, they did not disappoint. Anyway, I was researching the hissing problem and ended up here, and because of you guys, I have already dropped money on a new pair of headphones + now considering an amp, a term I did not even know the meaning of a month ago. Should I just grab my wallet, do a 180, and run far FAR away? ;)
