I just picked up my RWAK380 today and am heartbroken to report that I have encountered these 'fatal' problems:
[COLOR=222222]1) There is noticeable clipping / feedback using my Westone 4R and Shure 846, the clipping is most severe with the Westone 4R, where with some piano and vocal tracks there's a constant carpet of buzzing from start to finish, and it is detectable even at low volumes, almost sounding like a very fuzzy / loud noise floor. The buzz has rhythm and with some listening it is obvious it is a feedback mimicking the notes being played (mirroring the music in length and decay). Initially I thought this was my iem's drivers being busted, so I went to a shop and demoed multiple of their iems. The problem was replicated on even the K10 and SEM6 (the shop speculated that this was due to the RWAK380 output being too powerful for my 'middle tier' iems and that maybe the problem will go away when I try some multi-armature / difficult to drive iems). The only iems that were almost free of this noise was the new full metal jacket JH Siren Series Angie. I then plugged in my Layla and the problem was also less severe than the Westone 4R. I have plugged my 4R into other sources like the shop's AK240 and my iMac into Mojo and the 4R performed fine and clipping free. [/COLOR]

[COLOR=222222]2) The battery dropped at a frightening quick pace. This was so exaggerated and alarming that I really think something is terribly wrong right away as the RWAK380 site cites the battery is not affected in any way. A 3-minute song (ALAC 16/44.1) used up almost 5% of the battery. When I first turned on the unit after pick-up the battery was at 93%, I have used the DAP for maybe a combined total time of 1.5 hours at most and the battery is now at 12% (I have received the 15% warning already). No power-hungry stuff like DSD or 24/192 tracks were played to expedite consumption. [/COLOR]

[COLOR=222222]3) The unit got searing hot just playing 1 - 2 tracks, I have a feeling this might go hand in hand with the battery problem, since overheating burns a large chunk of battery off electronic devices very quickly (I have experienced this when my iPad was incessantly trying to connect with Wifi on a plane and the tablet got irregularly hot and burned through battery like a hot knife through butter). This was a similar case. [/COLOR]
Now I don't know if these are natural trade-offs and consequences that are direct results of the modification, or if it's just my modded unit being defective, so can any other RWAK380 owners share their thoughts? @speedracer1 @Apina
I have contacted Vinnie and am so very anxious to find out what's going on.
Whether it's nice is highly subjective. Tho the salmon pink marks we see from that demo unit is more likely the actual color of the pure copper showing through once the surface shiny coating wore off, and not rust from oxidation. I remain highly intrigued by an SS version should they make one. I love me some blinks
