A much belated thank you for the reply, I was on vacation.
The good news is that the QB2 is in better shape than I thought so I'm not in a big hurry.
The TTPod does seem like a great IEM, but I'm not sure I'd feel comfortable buying Chinese IEMs from anywhere other than the trio of Penon, LMUE, and MP4Nation, and they cost quite a bit more over there.
Speaking of MP4Nation, I've noticed that they have a couple of KZ IEMs, though not the ones currently being hyped up and at a higher price than from Ali sellers.
Anyway, seems like my options are the TTPod, trying my luck with some KZ off Ali or maybe jumping on the discounted VSD3S from Penon. Some KZ model would probably be ideal (consider that for stuff above the equivalent of 22€ the price jumps up due to the VAT), but the reports on the sellers seems very mixed at best. This is a tough one.
