With the overweening success of the Fostex TH900, all in the land of headfi hoped and wondered if some of that magic would trickle down to something a bit more manageable. So it has. At close to half the investment, Fostex has taken much of the magic of the TH900 and scaled it down for those of us with more accessible budgets. The magnet used is not quite the monster that the TH-900 has but the sonic signature is all Fostex. From the Fostex web site:

"Viewed in its own light, against similarly priced closed back rivals, the TH600 fares very well and may be my favorite Japanese high end closed back at ~$1000. It definitely is a win over Audio Technica’s W5000. More correct tonality and timbre, and a more linear bass extension than the W5000. It’s sort of a pro-and-cons situation with the W3000ANV, where the 3000 sounds more luxurious and is richer, but is plagued with issues like bass extension and a midrange dip. Not an easy one to decide, between the TH600 and the W3000ANV but I’m leaning toward the Fostex. Compared to the Denon D7100, overall the 7100 has a more lively tonality with a stronger bass impact, and a more sparkly treble. I think the D7100 is the more musical headphone compared to the flatter sounding TH600, but the timbre sounds more plasticky in the D7100 and likewise the build is far from being worthy of the price tag. What can I say, it’s a tougher battle field down in the $1,000 price range especially between the W3000ANV, D71000 and the TH600. At the moment I’m leaning toward the TH600, but that may just be new toy syndrome."
