well, compared with the Hugo 2, the th900mks 2 have extremely powerful bass on the TT2/M-Scaler. I thought the bass was powerful out of the Hugo 2, but I didn’t know to the extent that you get from the TT2/M-Scaler. The bass is similar in power and quantity as my TCs on the WA33. I feel like the resolution is noticeably worse on the Fostex, compared to the TCs and Utopias (which I guess is to be expected). Others mention problems with the sharp highs, but I don’t notice it on mine (somebody suggested that since I have the blue ones, that is why the treble sounds good. I dunno though). Mids are recessed, which is also no surprise. Also the headphones aren’t the fastest, in terms of timing I’ve had a lot of headphones in my life (rs1e, lcd2, hd800, cascade, utopia, th900mk2, TCs, Koss 95x, etc.) and when I got the TT2/M-Scaler I sold everything off except the Utopias and Th900mk2, which I think says a lot. I then bought some TCs and still decided to keep the Th900mk2. I listen to a lot of metal and hip-hip, and the Th900mk2s are perfect for those 2 genres out of the TT2/M-Scaler. Now that I have the TCs and a WA33, I don’t listen to the Th900mks as much. I’d say the TCs on the WA33 have similar bass as the TH900mk2 off the TT2/M-Scaler. The TCs are faster, have outrageously high resolution, better highs, better mids (the Utopias have the best midrange though) I keep the Th900mk2s though, for 2 reasons. They are easier to drive than the TCs, and they’re my only pair of closed backs that I have left. I think the $1500 for the th900mk2s is a great deal. The utopias are $4K and I don’t think they are 3 times better. The TCs are like $5K and they are not 4 times better than the th900mk2s (though it is close).
