Nice, can you recommend any for Mac?

My first amp was the E17.  I liked it and enjoyed the treble, gain, and equalizer settings.  Next I purchased the E6 to save money and space.  To my ears I cannot tell a difference in sound quality on their neutral settings, although I have never done a proper DBT.  Honestly, I like the EQ...

To be honest, I like the EQ setting of the mid-range boost on the E6 rather than it's neutral setting.  So I guess with the Ultrasones I like to boost the mid range a little.  If the Magni is that neutral it may not be to my liking.  Would the 900's still benefit from more power?  What amps are...

Will a $200 dollar amplifier provide any noticeable improvement over a Fiio E6? My headphones are Ultrasone Pro 900's and my source is a Mac.  The volume with the E6 is more than enough for my ears so is there any other reason to have an amplifier other than higher volume?  From DBT it seems...

Thank you, but more specifically what would be enhanced?  I feel the volume from my Mac into the E6 is more than I ever need with the Pro 900's and I tend to listen pretty loud. Other than the Magni looking nicer and more solidly built what could I expect in the difference in sound quality...

Would anyone know if I'd benefit by replacing a Fiio E6 with a Magni to pair with a Ultrasone Pro 900?

I'll be running them from itunes into a Fiio E17.

Right on.  I'm getting excited now.  Ever since I purchased a pair of Monitor Audio Rx-6's I've been looking for a headphone that can match their level of excitement and detail.  Hopefully the hfi 780's will just what I'm looking for.  

Thanks. If the Ultrasone's don't workout I may give the Beyer's a shot.

I went with the Ultrasone HFI-780. At the price they are worth a shot.

Hi everyone.  I almost just pulled the trigger on a set of Denon Ah-d600's earlier. But after some more research I thought I may be able to get away with something I would like just as much and save some cash.  One set that looked appealing and cheap are the Ultraphone HFI-780's.   I listen...
