Not really, imo.
The specs mentioned by SoundandMotion are the max output specs.
I'd recommend higher than 10volts for such a high impedance headphone.
As i stated for the T1, the impedance of the dynamic driver got a hugh swing on certain frequencies.
For the T1, it rises up to nearly 1300ohm between 50Hz and 110Hz.
As you can see on the paper from innerfidelity, the 880 600 rises up to 750ohm.
So these are the specs you should calculate with.
A nice quote from RAA:
"
The resistance affects the amount of current that the amplifier should give to the headphones. If the current is not enough, the sound quality will deteriorate, beginning with harsh in the sound and ending with a crackling. In most cases, at low current values, the amplifiers operate in comparable quality to class A, and as the current level rises, the quality decreases toward AB, B, and the clipping zone.
Imagine that you have a water tank, which gradually fills with water. The voltage from the amplifier this is the pressure with which the pump draws water from the reservoir. If the inflow of water in the tank is lower than the volume that the pump pumps out, then at the pump outlet we collect water and "bubbles". Similarly will be with the sound from the headphones, which are lacked the current from the amplifier."
