I have a Opera Consonance Cyber 30 SET amp specs are listed below. Would this amp effectively drive the HE5le or HE6 headphones?
CONTROL FUNCTIONS: Volume, Mode Switch(normal/headphone),Power On/Off
POWER OUTPUT: 3.5W x2 RMS 1kHz
TOTAL HARMONIC DISTORTION: less than 1%( 2 watt, 1kHz )
FREQUENCY RESPONSE: ( -3dB points at 2 watt ) 6Hz - 35kHz
INPUT SENSITIVITY: 600mV
INPUT IMPEDANCE: 100k ohms
OUTPUT IMPEDANCE: 4,8 ohms. User selectable.
CONSUMPTION: 86 watt
INPUT INTERFACES: 1 group (RCA) - (on the rear panel )
INPUT INTERFACES: speaker terminals - ( on the rear panel ) and headphone jack - ( on the front panel )
OVERALL NEGATIVE FEEDBACK: None
VACUUM TUBE: 2A3 x 2,ECC83 x1

It should do reasonably well with the HE-5LE, but I probably would not recommend it for the HE-6.
