A83 is not power hungry, but would benefit from a warmer/neutral source to tame down its top end brightness. From HO of AP100 it might be a bit too bright, with E12A you are getting more into a neutral territory. With Cayin C5 - it's even better. Gotta admit, haven't tried fw70, wonder if sound has changed back from early days of previous firmware releases.
If you want to push your IEMs to 3D limit, you need a DAP with a dual-DAC where L/R channels processed separately for a better staging control. Example is something like Cayin N6 or AK120ii, or the upcoming FiiO X7. At the same time, we are talking about a significant price jump from AP100...
Hi Twister, thanks for the info.
Yes the FW70 is well worth the upgrade but Fidizs recommend FW69 first. I only have experience with FW67, 69 and 70. FW 70 seems to me to have a fuller sound, better bass, better transparency and 3D sound.
Could you reccommend any good value IEM's (for occasional use) from your experience for the the AP100 un-Amped that has a neutral sound with good mids and controlled bass and top end.
Any IEM's I have heard sounded unnatural and tinny.
