My office setup is the Mac to CA DacMagic to Fatman Carbon v2 into MA RS1 and I love the way it sounds - its plenty load enough and good enough that the music draws my attention away from what I'm doing at the compute often. Now, I don't want to over sell it, my office setup isn't in the same league as my living room Naim Nait XS/Benchmark DAC/MA RS6 (soon to be replaced with I'm leaning towards Spendor A5). I think the Fatman MA setup would be perfect for what you are talking about, I love mine. I did look at the MA BR2 as well and they too are great but I found the RS1 a little easier to drive with the Fatman and importantly there was very little price difference when I bought mine. Either would be great and certainly go load enough, my only qualifier would be that the Carbon/MA is good enough to highlight the differences between using my iPod and feeding an optical connection into the DacMagic.
