I'd say this try out someone else's amp and see if you like or can even tell any difference. If not then it's probably not worth it to you. Beauty is in the eyes of the beholder right? (or in this case the ears) However, if you listen and notice that everything seems clearer more articulate and punchy, then you know you've been missing something. I will also second the above post in that it isn't worth it spending tons of money to amp a mediocre source. That doesn't mean that buying a cheaper amp to get a little extra out of your computer isn't worth it at all. I will say this though. The majority of good sound quality does come from the transducers by which you're listening to, however having said that there is a significant amount of SQ left after upgrading to top shelf headphones, earphones etc. and that's where the huge mess of amps DACs and sources come in. Everything in this audiophile world is incremental. It's pretty similar to tuning up a car. You have turbos, tires, NOS, transmissions. No one thing makes or breaks the system, sure some are more significant than others and by having the Beyers I think most would agree that you already have one of the more significant components to good audio, if not the most significant.
