Hi, Need recommendations on a a headphone and amp!!, Have ipod touch and note 9 cell phone!!, budget is no more than $1500, thanks much!!

I am looking for a good portable amp for the v-moda crossfade m-100's, my budget is no more than 300 dollars but cheaper is fine as well!   thanks

Hi,   been a long time since i posted on here, my previous headphones were the denon ahd-2000's , need a good suggestion for $700 or less for both the headphones and portable amp, i use my headphones primarily for my ipod and laptop and sometimes my home stereo   thanks for any help

After 2 years of loyal service my denons have kicked the can, need some help picking a new pair of phones!  I will be using them for my ipod and laptop , and they will be powered by my portable airhead pro amp, I wish to spend no more than $500USD, thanks for any help you can give
