I have been looking around for a decent pair of headphones to use while listening to my records. I have a fairly nice setup so I want to make sure I get the impedance right so that I'm not losing out on sound quality. I will be using them exclusively with my McIntosh MAC1700 receiver which I would assume can handle 600 Ohms, but there-in is the problem I am only assuming and I do not want to spend the $$ and whatever burn-in time it will take without consulting more knowledgeable resources. The receiver is a vintage model with vacuum tubes here is some of the electronic specifics.
-Stereo. Hybrid (Solid state preamp and power amp, tube tuner). 40w/ch into 4 or 8 ohms. Response 20-20kHz (+0.5 -0.5dB). Distortion .25%. Noise and hum: power amp -90dB, aux -75dB, phono -76dB below 10 mV. Damping factor 100. Input impedance: aux 250k, phono 47k, tape head 500k. Input sensitivity: aux 0.3V, phono 2.4mV, tape head 2.4mV. Tone controls: bass and treble. +18 to -18dB. Filter: 60Hz at 12dB/octave and 5kHz at 12dB/octave.
Any advice would be greatly appreciated.
