I was at an estate sale a couple of days ago, and sitting the a table was a pristine pair of AKG K240s headphones.  I snagged them for $5.  I attempted to use them on my MacBook air and my iPhone, but the volume output is super low.  I then amplified them with my Fiio E7 portable amp.  The volume is much better, but even with the amp maxed out it is still a bit low.  Any of you have a good amp recommendation for the K240s headphones?  Portable and desktop versions are needed, and $250 is about the max I can spend on either.

Thanks.

I'm using a $99.00 amp with my 240s called Magni by Schiit Audio and the two sound great.

The C&C BH is a great little portable amp for $100. I have one and like it better than my E17, which is generally considered a better headphone amp that than the E7. You might ask in the C&C BH discussion thread to see if anyone has upgraded from the E7 and what kind of difference they think it would make: http://www.head-fi.org/t/644363/c-c-bh-portable-headphone-amp-80-hours-from-a-single-charge-buyer-review

Speaking of the E17, have you considered getting a separate DAP to use instead of you iphone for portable use? The soon-to-be-released FiiO X3 uses the same hardware as the FiiO E17. So the headphone amp is all built in. See these two threads for more info:

I'm assuming you have 600-Ohm K240s.
My Fiio E11 can drive my AKG K240 Monitor 600-Ohm headphones, so maybe go for the newer Fiio E12.
My O2 amp can very easily drive the AKG K240 Monitor 600-Ohm also.
I think of the O2 amp as a good "semi-portable" headphone amplifier.

ALO Audio MKll portable amp (now $100 off the old price) drives my 35 year old AKG K240 no problem.  Have you dated the the 240's you picked up?  Wikiphonia has the pics.

The amp has to be able to handle 600 Ohms, the ALO MKll can but even that is pushing it.  The vintage 240 needs a heavy amount of amp.

Old thread, but I just wanted to verify that the Fiio E12 pushes the K240 sextett very well and they seem to have great synergy (better I find than with the C&C BH).
