    Can the sound card in my late 2012 iMac drive a pair of 250 Ohm headphones, or do I need an amp between the computer and my phones?

    It will work on the default output on the iMac but I've read before that it's a few DB lower unless you use an amp/external sound card.

    Our 2012 iMac isn't here yet so I haven't tried it with my 300ohm Sennheisers.

    On our other iMacs, the computer delivers more than enough volume.

    Nevertheless, I use an external DAC and amp. The difference in sound quality is immediately apparent.

    Can you Solder? I've built two of these, one for home and another for work.

    Not audiophile, but much better than what Apple uses.

    Glass Jar sells some headphone amp kits too. I'm using something else.
