Using headphones via speaker output channel 2?!?!
I've been wondering if it's possible to use a standard hi-fi amp. for headphones? The idea is that instead of using a headphone amp. you would use your headphones in the same way as you would use passive speakers (instead of using the headphone socket on the front of the amp. [that usually sound poor]). You would use banana plugs and instead of connecting speakers to the other end you would connect your headphones using either a custom 3.5mm jack or 'editing' the headphone cable.
Would this be feasible and/or sensible? I would like to do this but don't want to kill myslef or my headphones doing so. I have an old Marantz PM4001 that I would use and my Grado SR225s, as mentioned above, the headphones would be connected via the speaker outputs instead of the headphone jack. If this is a stupid idea I won't try it but if it's known to work then I'll give it a go.
Just a note - the PM4001 output is 40w @ 8 Ohms and the headphone impedance is 32 Ohms
Is this a stupid idea or does it have a chance of working? I would appreciate your advice.
