AV Receiver as headphone amp

I have an old Philips FR 968 AV receiver that I believe can work with headphones with an impedance of 62 ohms, notably the AKG k702. In the manual, it says under Receiver outputs: headphones 8-600 ohms (3 V e.m.f., 60ohm)

 

Will my receiver be more than enough to amplify these headphones, or should I consider buying an amplifier in the future?

I have 2 AV receivers (6.1 Sony and 5.1 Yamaha) and both synergize very well with my Fostex T50RP, which demands huge amounts of current energy (more than the 702 I think).

 

Also my Aurex Hi-Fi amplifier synergizes very well with them.

the Fostex T50RP require 50 ohms of impedance. atleast Im pretty sure this is the number we are supposed to be looking for...

Yes, you should look at the impedance, but also at the amount of power that the headphones can handle. The Fostex T50RP can handle 3000mW, which is a brutality and make them a little bit hard to drive if you plug them directly to a PC or a mp3 player.

 

Your AKG K 702 are 62 Ohms of impedance and can handle 200mW, so you should be more than able to drive them with your AV receiver.

Those old Philips receivers, amplifiers, CD-players etcetera usually have good headphone outs and are quite handy when you do not have a dedicated headphone amplifier. 

 

It gets better when you can modify the Philips audio gear because the better Philips products already have good internals from what I have read.
