Yal that sold your he4s to nab a 560 better hope that 500 dollar upgrade is worth it... Audio-gd 10se plus he4- TO ME, is end game...Im done with the he4 setup, i may buy an ember still, because i want to tube roll like a cool kid, but thats not a necessity for me. I do wish, i could find an amp as clean and clear as this audio-gd, but with the bass "punch" the mini-x had. Too bad the mini-x bass sounded off, like to much? not good quality, something, at first i was like "damn the mini-x has that bass!" until i gave it a while and found it just didnt sound "right". The 10se, sounds right, but lacks on the lower end, which is fine, i dont need to be a bass head, and im sure i can eq it in. Anyhow, looking forward to a few months from now, when we can trust the 560 reviews, and maybe see some direct comparisons by people who actually have heard, and enjoyed the he4. Until then, ill enjoy what ive got.
