I'd love to know how you came to this conclusion, as ALO doesn't state the output power of this amp. They say it has a minimum of 5.25v and over 200mA of output power,and peak of 7.45v, but that's just a phrase. They don't post any proper measurements of output power like this:
Maximum output power per channel from 20-20,000Hz:
160 mW_16 ohm
80 mW_32 ohm
12 mW_200 ohm
(this was taken from the iqube website)
so please share with the rest of us how you can affirm that the ALO Rx has more power...
Also, IMO, none of these amps are suposed to be driving full sized headphones. They are portable amps designed to be used with portable headphones or IEMs, and although they might sound "good", they cannot match the proper power and voltage swing of a desktop amplifier.

But I do think iQube can't drive K701 better than alo rx, the iQube just not up to the task in term of power.
if you are ok with desktop, why dont you build a 2 boards beta22, ... its prolly cost just a bit more compare to a new iQube.
