hey guys. i've been using japanese A16 for a couple of days, and i want to post my early impressions BEFORE some burn-in to help guide people with some insight, so to say what they may observe when they first bought this product. In other words, these impressions are from a non-burned, out-of-the-box A16, which carries POSCAP capacitors and is advised by Sony to be used a few hundred hours to reach its whole potential.
first of all, this dap is REALLY small and lightweight. the pictures do not do justice in showing that. you should take it to your hands to see.
SOUND :
Note that these are from headphones exclusively, using Grado Hf-1, Audio Technica Esw9 and AKG Q701 (each rated equal or greater than 32 ohm impedance). Things with iems may highly vary.
1) Objective Impressions :
For previous F886 users, I am happy to say that A16 has a significantly more powerful amp inside. Leaving aside Grado, and Audio Technica (which are easy to drive), A16 is even enough for driving AKG Q701 to somewhat pleasurable levels!!
Right now I am listening to some classic pop, rock and orchestral recordings, and I can say that (with 27 vol.,dynamic normalizer on, + some eq, clear bass + 2, all other effects off) this tiny boy gives a certain level of juice for AKG Q701 to sing. It is apparently MUCH louder than what F886 can provide for these cans. However, with Clear Bass +2 and +3 it shows compression and sound level flactuations after 25 - 26 volume, like the one in A845 or X1060. Yet I did not observe this on cans other than hard-to-drive AKG Q701. This should be the point where the dap's internal components start to yell "aaaaaaammpp mee pleeeeasseeeee" : )
Like F886, I found A16 to be the most successful in creating the realistic ambiences of live recordings, trumping Fiio X3, Ibasso Dx50, and even technically much superior Dx90 on that matter. On all of the three headphones above, it becomes a joy for listening the actions and clappings of audiences in the live records with both of the Sony's.
2) Likely to be Objective Impressions :
I feel the frequency of A16 is more even compared to F886, which has some kind of percievable hump in the upper mids just before the beginning of a roll-off in the treble region. A16 I think, too, has that hump which makes the Sony guys to sound forward, and especially mesmerizing in live recordings. Yet, I think A16 is more even in frequency, and probably has a bit more extension on the treble region. At that moment of writing those, treble of F886 (fully burned btw) seems to be more relaxed, smooth, detailed, and slightly less extended compared to the one of A16.
3) Pure Subjective Impressions
I "feel" compared to F886, A16 retains a similar soundstage with comparable width, and depth. Though not sure, F886's can be a bit wider, but A16's stage is admirably even in width and depth.
Besides, detail levels seem the same both on F886 and A16 ; in that manner they resolve some good level of detail in recordings.
However, at that time, I very subjectively think that my non-burned A16 is less transparent and clear than F886. Openly speaking, F886 has been the most clear and transparent sounding dap (with headphones) I've experienced till date, and A16 is slightly grained in sound compared to F886 right now. I will post more of this issue as I kept burning A16.
Also, at the moment F886 seems to be more refined across the entire spectrum compared to A16. Though not much, this may be the only immediately recognizable sound difference between F886 and A16. Overall, I think A16 is nearly in the same level of sound quality of F886.
I'll post more as the time goes.
