i am new in the audiophile world i have a pare of audio techinica Msr7 cans i have high quality files and use tidel hifi but i need a better hardware because i am using the sound that is built in on my MB I would like to spend no more then $150 and a $100 if possible i was looking at the Micca...

I can get a pair of barely used audio technica msr7 headphones for $100 is that a good price or should i get sennheiser hd 558 i know they are not the most comparable headphones but i think the audio technica headphones are good for $100

I need some new headphones and a Dac. I like the sound signature of the Mee m6 pros. I am really new too this stuff but i almost got the hifiman he-350 off of massdrop but could not find any info on how they compare to the sennheiser hd 598 or Phillips shp 9500 i do not really know what to get...
