David, i was just about to buy the HE-400 but now you're making really wanting to buy the iPhone speakers. two of them is pretty expensive, but i think for quality, the price is justified.
Sort of like computer processors don't you think? The ones costing $1000+ (Black Edition, Unlocked Multiplier, Etc) are only 5-10% better than $200-300 priced CPU's. Then again, you would have it better there in the computer world because you can make both worth more/bang for buck (overclocking) while in the audiophile world, these don't overclock.
So i believe the price should be where its at. (except the orpheus) cough cough.
Those iPhone speakers have heart thumping bass, be careful! :)
