Quadfather
Headphoneus Supremus
Still slippery, but seems accurate. I lick my finger and wipe on my jeans before each use and it functions perfectly, until the next lick.
It is normal. Probably more obvious with sensitive iems. But heard from others v2 has lower noise floor, so not that apparent or gone.
I received one of the newer units with the improved click wheel and it seems fine. several recordings have a little hiss, but I've determined it's in the actual recording, because really, really super well recorded albums like Michael Jackson or Dire Straits have zero hiss
People who are more sensitive to hiss will hear it with the QP1R and SE846. Is it not a problem with your device or your IEMs.
you make a choke - QPR1 is on the high level of AK380 high-tier
Sony ZX2 is a coloured mid-tier
In my opinion, not even the AK380 -- the QP1R sounded more detailed and coherent to my ears than the AK380. The AK380 Copper has been the only DAP that has comparable sound quality to my ears out of all of the DAPs I've listened and compared.
