Yaay a troll =D
I was honest enough to admit I had never heard them, which a lot of people in this forum won't admit. And I don't need to have ever heard a Stax headphone to know it is amazing. I have however read a lot about the SR60i and the SR60 and the SR80/80i, and there was a general consensus about lacking of bass, even with the upgraded driver in the "i" series. If the OP had asked a more complex question I wouldn't ever get in the middle of it, but he stated to be a noob and I told him what I have read here, which was very straight-forward. Apparently all the commenters above own the magical models of the SR60 which leads them to believe they have huge ammounts of bass, because I've read a lot more people stating they don't have.
I clearly stated I haven't tried them, what's the big deal? I just said what a lot of people hold to be the truth about these, and never pretended to be the Grado God you seem to be.
Second I never stated there was no difference between FLAC and 128 MP3. Never. Go read my post. I stated that since he is a self-admited noob and is running it through a PC stock soundboard, with no external amping or DAC, he probably won't notice the difference. That's all. No one here will state that FLAC and MP3 are the same, of course there's a difference, but try catching it on Apple iBuds.
Third, maybe reading the OP's post actually? He listens to Trance. Trance. If you are even suggesting the SR60i are the best choice for Trance, you own a pair as much as I do.
Howdy. for your viewing pleasure, a graph comparing the Frequency response of the sr60i and HD650
Just in case you've never seen a frequency response graph before, I'll give you a simple run-down. The left side is where the bass happens, the right side is where the highs happen. The bass is maybe 5db lower than a HD650, so your saying they aren't known for their bass might be true, but it isn't really a fault compared to other headphones. Another thing I'd like to say is that you really need to at least hear a headphone before recommending (or not recommending) them to new users. I find it funny that you praise STAX systems so highly, when a common fault is their bass amount (in the lower end models). Disclaimer: STAX still are awesome, but the bass is lower than the rest of the spectrum.
Lastly, trance sounds good on these. There isn't massive bass, like many trance users like, but the bass is tight and not boomy.
Sorry OP, I didn't want this to turn into a big argument.
