headphones-amp combination


I have been curious and following several headphones and amps on the net just to adquire some knowledge about them.
Now I decided I want to get a portable amp and a paor of headphones that match the same level of musicality of high end separated or tubes.
I am a novice in this field.
Thanks

Recently got back into to headphones.   Picked up a pair of Grado RS2e along with a Massdrop Objective 2 headphone amp.  Great combination driven from my tablet or especially when driven by my NAD M51 DAC.    
Since my last comment in 2011, I have purchased a pair of Stax 009s. I can’t imagine anything better but I’m still looking for better amplification (like Blue Hawaii).  I’m happy for now. My other favorites are Fostex 900 and HifiMan 1000 V2, both of which I heard a few years ago at a hifi show in Orange County. The Audeze phones sound great but the pressure on my head was just too much.

For personal listening on my iPad, I use a pair of B&W phones.
Keep it simple but with great results. Use an I Phone or Android phone as your source. Stream Tidal or Spotify. Output to a portable Mojo amp. Headphones of your choice plug into the Mojo amp. The system will fit into your pocket. Mojo amp is about $550.00. Made in England. A mega big seller in the headphone community. Drew Audio in North Carolina is a major headphone specialist. Check out their web site. This is the portable rig I use.

Recently ordered a Rupert Neve Designs RNHP headphone amp......  can't wait to try it with my Grados.    
Update:

The Rupert Neve Designs RNHP headphone amp is phenomenal.    It took my Grados to a new level.   This amp makes everything more intelligible,  it is spooky the levels of detail it unlocks from material you thought you knew well.  It 's roots are in the studio environment so it is built like a tank, it is one solid unit.  The volume control is super smooth and it has that "instrument" quality feel to it. 

It can drive the Grados easily and can drive my 600 Ohm Beyers with ease too.  Sure $500 ain't cheap, but I think it is worth every penny.
