Wow you ordered the 8As? lol
Yeah I've been told the 8As should pair very nicely with them. If so an no audible hiss I'm gonna be very happy as that is 2 IEMs that go very well with it :). You are right on finding the perfect match with the Studio V. It isn't easy as its a very energetic DAP. Very potent stuff. But find the right pairing and its unbelievable the sound you can extract from them.
yea the promotion on the 8a is just so hard to resist. the jh16 have sibilant when paired with the studio v, the 8a is bass heavy and have smooth treble similar to the ie80 so i hope their pair well.
