I was thinking about getting the DT880' s or 990' s will my EF1 drive these or should I be looking for the 250 Ohm cans? Maybe it would help if I gave the specs. I don't know what this stuff means so maybe you guys could help me out here.

Opamp: OPA275
Tube: 12AU7 (SINO)
Frequency Response: 20-30K Hz
THD+N: less than 0.2%
S/N: more than 95dB
Input impedance: 50K Ohm
Output impedance: 2–2K Ohm headphones
Output signal strength: up to 15 Volts at 32 Ohm

Thanks
