Impressions for now. Measurements will come later. One thing I want to remind readers is that any subjective impressions I have to offer are only real within the context of SBAF, what I consider to be good sound, and how readers understand where I am coming from. The impressions there forth should be not considered as any kind of absolute truth. The search continues for a decent sounding relatively low cost headphone amplifier that does "headstage" well. This statement of course implies that the G111 does not qualify as decent sounding. One prior candidate for "headstages well / affordable" was the Fiio K5 Pro, reviewed here: https://www.superbestaudiofriends.org/index.php?threads/fiio-k5pro-review-and-measurements.11326/ I was hoping the G111 would sound more like the V281/280 rather than V200. Unfortunately, it sounds more like the V200. The G111 doesn't even do headstage well. Well, this depends upon your definition. The G111 has a wide wide headstage. It's got a holographic effect as if there was some sort of DSP. Unfortunately, this holographic effect only spans in one dimension, from left to right. The headstage sits on a plane right at my ears. There is zero front to back layering. There isn't much separate either. Imaging is diffuse on that one plane. And because the plane is flat, there is no sense of openness. However, those who really love a wide headstage will find themselves happy. While I do not expect headstage to sound anything like soundstage (speakers), I at least would like headstage to have some depth and a degree of openness. I ain't getting either. No matter what source I tried, the G111 strongly imparts it's own sound. This is very much unlike superior headamps such as the Bryston BHA-1 which I recently reviewed. Whether I used the Modius or Yggdrasil More Is Less, it didn't matter much in terms of technicalities. Tonal signature matching is somewhat effective. I found the more neutral less "phat" Geshelli JNOG DAC to have best tonal synergy with the G111. The G111 offers both XLR and RCA inputs. The RCA input sound slightly more resolving. The XLR inputs are less resolving but more cohesive sounding. I will explain this later. Overall the G111's presentation is warm, polite, and forgiving, perhaps overly so. That in itself would not disqualify it because a lot of OG Cavalli amps were voiced this way. There are several issues which plague the G111. The first is an artificial timbre in the highs. This one is hard to explain. It's not that the high highs do not sound rough or harsh. It's that they sound fake. It's as rather than be truthful and incisive sounding when the recording calls for it, the G111 pulls it back and applies an AI filter to smooth stuff out which ends up polluting them with a robotic texture. The second issue is that the G111 sounds slightly a bit on the flat and boring side. It's as if the G111 combines the worse qualities of high AmirNADS amps that use opamps and colored discrete amps. It would be interesting to measure and open up the G111 later. Finally, saving the worse for last, the lows are just g** d*** awful. I could not get past how the G111 took the lows, put them into blender, and pressed the mush in baby food button. This aspect of the lows causes a bit of disjointedness with the highs. The XLR inputs impart a slight veil on the highs which seems to even things out a bit more. After measurements, this goes on the loaner program immediately. @rhythmdevils: can you set up a loaner thread for this?
