Pretty much the title.
If these are the salient differences, is Axe I/O more high fidelity than the One? I know they're both 24-bit, 192KHz capable but i was wondering if perhaps the mains power was "better" as it's not another device drawing power by way of USB.
I'm not really concerned with portability, just sound quality and processing power as it's hard to justify the extra $ otherwise.
I appreciate your help!
