Thanks for the reply! This was really reassuring, especially hearing the difference between them would be pretty small, and even the 009S is driven "fine" for it. From what I was reading, it does seem like the differences between the different Stax-official drivers, there's not a substantial difference. I ended up going for the T1S+L700. It actually did come with a bonus oldschool Stax (SR-3) that's in really nice condition. They warned me it has a ground hum in the left channel occasionally, I haven't heard it yet, but not sure what the cause could be for that. Maybe someone here has some ideas? I guess I'll know more when I encounter it myself. The SR-3s still sound nice, even for their age! More mid-focused. And the L700+T1S sounds absolutely terrific! I'm very happy with it. The T1S was boxed and unused until the previous owner bought it from a collector a couple years ago, so I think it should be in good shape for a bit. The tubes were also replaced with higher-quality tubes, and they included the (unused) originals with the sale to me. I didn't realise there was a dedicated thread for this, thanks! Checking it out now. I did read they had minor differences, but if anything the L700 should have a slight edge. The L700 set I bought came with a second pair of brand-new L700 pads, so it seemed like a better deal anyway. I figured the a minor upgrade in the headphone will make a bigger difference than a minor upgrade in the energiser. Interesting to hear, I wasn't super excited about the 007/009 when I tried them at the store too. They felt smoother than the L700, but maybe for my tastes in music (particularly electronic), they didn't have the same draw. I didn't demo them for more than 15-20 minutes though, so that's just my very-brief first impressions.
