Looking at the following:   Sennheiser Momentum On-Ear  Onkyo ES-FC300  Sennheiser HD 280 Sennheiser HD 429 Bose On-Ear Sol Republic Master Tracks   Music type = Jason Mraz, Ed Sheeran, etc.   I’m would be using a Nuforce Micro Dac 2/Headphone Amp and a Macbook Air.

Using a Bellari HA-540 Tube Amp, Nuforce USB DAC, and my Macbook Air / iTunes.  Is one a better choice?  Music: Pop, ie. Maroon 5, Adele, Dave Matthews, etc.  Thanks!   PS. I have the Shure 750’s, hate the comfort.

Considering these 2 headphones, any input?  I listen to music like Adele, Maroon 5, Jackson Browne, etc.  Using a Bellari HA-540 Tube Headphone Amp.

Audio Technica ATH-M50 vs. Shure SRH750DJ vs. Onkyo ES-FC300    Looking at the above headphones.  I will be using an Bellari HA-540 Tube Headphone Amp, and a Firestone Dac, Mac Mini.  I listen to music like Adele, Beatles, Maroon 5, Jackson Browne, etc.  Any recommendations?    Thanks!

Looking to spend about $250, just purchased the Bellari HA-540 amp.  Anyone have suggestions?  Thanks much! 

  Having some buyer remorse.  I picked these up on markdown at Radio Shack for $89, which I guess is a good price.  But, they are very bass heavy, and lack mid and high detail for the music I listen too ... Adele, Jack Johnson, Jason Mraz, etc.  I'm thinking of returning them, but at that...
