Thanks for your response! In the meantime I have performed some tests using RTL utlity to measure roundtrip latency and the results are not encouraging 
. All those tests has been performed @48 kHz using i8700/16GB system.
- 24 samples - 11,208 ms
- 32 samples - 11,542ms
- 64 samples - 12,875ms
- 96 samples - 14,208ms
- 128 samples - 15,542ms
- 256 samples -20,875ms
- 512 samples - 31,542ms
- 1024 samples - 52,875ms
As you can see, the results are really, I would say, disappointingā¦ at least for me. I Have also repeated those test using ASIO4ALL drivers and the result was almost the sameā¦ a bit worse but little slightly.
Interesting is that I have tried to find something about components used to build interface in this device but I not found anything at all about this. Nothing about DSP chip, nothing about A-D-A converters. Usually, there are some information about such a things in the reviews but not in this caseā¦ there is nothing about this on the internet.
