I believe it was someone from Head-Fi a few years ago said (I am paraphrasing) that headphones are awesome because we can get the sound quality equivalent of a $40,000 speaker system for a tenth of that. Considering how much headphone pricing has escalated...
I call BS on that.
I got seriously into headphones after my second child was born, and how much I have forgotten about speakers!
This modest setup ($500 speaker kit, Crest CA-2 power amp [$500 ebay], Schiit Mjolnir as pre $750, Schiit Gungir $750) beats the crap out of any headphone rig for me. It's not finished yet as I need to add a supertweeter and will try to integrate a subwoofer (I know REL's secrets.) It does some things worse than TOTL headphones, but it also does some things better. It sounds great at low volumes for that 2am magic hour listening. And low volume means I won't wake up the rest of the family.
I strongly encourage everyone to quit this HF mickey mouse shit, get rid of (or augment) their headphones, and start building easy speaker kits (of any sort).
