Yes ldac, it sounds amazing especially with neutron. I can't detect any difference from usb. I could go on a long rant about clocking and the USB path verses data from the Qualcomm chip, all paths go through an fpg chip and clocking chips....
But just let me say this is a very good BT implementation. And if timing were off (and I suspect it's not) it would be cents at the most and probably .9 and less in pitch change which isn't detectable, unless you're one in a million.
If something is or is not decectable depends on many things and we are talking only about one of them but each of us has all the other things different. So our views are not so well comparable.
What is important according me:
1. Which record - test in this quality class has to be done only on high quality records, acoustic music, jazz, classical, and so on. Forget about most pop, rock, rap, any electronic, these are mostly badly recorded.
2. Sample rate and bit depth.
3. Which player you use and how it is set, if there is some resampling within player or output is bitperfect.
4. Which operating system you use and how it handles BT. Generally Android resamples to 48kHz, maybe possible to set in player. What does OS with player output?
5.Quality of BT reception
6. Implementation of BT/USB in dacamp.
7. Quality of dacamp.
8. Output type - SE or balanced
9. Quality and resolution of headphones/speakers.
6. and 7. are the only constants in our case. If some parts are not as should be then the possibility of hearing differences is lower. So comparing I hear/dont hear does not have sense if at least most part are not the same or at least similar.
If somebody is satisfied with BT - no problem. I am not so much. I hear clear difference in handling of trebles. There are some tracks where it is hard to hear difference and other where it is clear. Tracks with lot of trebles like Beck - The Golden Change from Sea Change (MFSL CD edition 16/44 FLAC). Trebles are a bit distorted by bluetooth and clean by USB. Why if LDAC 990kb/s should be looseless? I can hear this within first seconds.
Gear used : Samsung S7, UAPP player I hope correctly set for loosless bitperfect also for BT, AKG K701 headphones on SE output.
Hopefully the next firmware update fixes the DSD512 issue. This Q5s is an amazing device. I'm truly impressed. Good Job
@FiiO ! Numbers!!
What do you mean by DSD512 issue? DSD512 is not in DAC chip specification. Only DSD256..
Are there any DSD512 files? I know only about some which were upsampled from DSD256. I think DSD512 has no sense in real world. Quality is not higher and 6 min. track has 2GB!
