I originally posted this on the full size amp forum by mistake. My bad.
I have $400 to spend to improve on my current setup - DB500s + FiiO6. I have been considering the AT A900X paired with the Magni/Modi stack. OR - would it be better to spend the extra $100 on better headphones and skip the DAC. I will be playing these from my Acer laptop and listening primarily to Pandora - trance, electronic, pop/rock, indie, dance. Portability is not an issue. I will be making this purchase on Wednesday but am still researching and would really appreciate some expert advice. What would you do with $400 to create the best possible sound with my setup? Thanks for your help.
