If I love the MDR Z7, would these be a great upgrade?

When you say neutral, do you mean it changes the sound signature to flat or neutral or neutral as in it won't affect the pre existing sound signature at all?

Alright. And what about the amp choices? Are they adequate based off your knowledge for these cans?

But not a galaxy s6 or other flagship smartphone?

Will these sound like trash if I were to plug them in straight from my Galaxy S6? If so I have zoomed in on two portable amps and thats either the fiio e12 montblanc or the vamp verza from vmoda. Would these amps be good options?

But still you wouldn't say that the h8 is terrible right? I use beats pro and want an upgrade 

Also how do these compare to the denon  d7100 regarding overall quality and fullness? 

Has anyone done a comparison between these and the new sennheiser hd630 vb?

This makes me want to ask. This or the sony MDR Z7

Oh and how would these compare to the Bowers and Wilkins P7?

These cans cannot be EQ'd to be basshead friendly? even with basshead amps like the digizoid zo2 or the zo fs?

What standalone music player is powerful enough to sufficiently drive the Z7?? 

PM-3 or the new Sony MDR Z7?

How do these compare to the mdr7520?
