Have you tried UAPP integer upsampling? What rate have you been upsampling to 24/384-352 or higher? Use frequency multiples of the original if possible.In short, I have nothing but praise for RS6. I will upsample my favourite albums to the maximum resolution RS6 accepts as I hear its benefit. It might also have to do with the program I used. PGGB does extreme filtering using a Matlab upsampling algorithm. The files that I used were upsampling with 256 million taps.
- I just wanted to understand how the OS of RS6 functions and whether only MQA benefits from OS for now. It appears only MQA benefits from the OS feature of RS6.
- I also wanted to feed RS6 the maximum playback file it accepts and compares it to the same file OS by RS6; I hear a difference.
- Hibys OS is warmer and more forgiving.
- Direct 2xDXD playback has a sharper attack, better transient response.
- I made a significant error on my DSD test. It was not a deliberate error but accidental. I'm after an excellent offline DSD upsampler that does not cost 2,000 USD. I was trying to test how good the free PCMDSD program I found online function, and as a result, last night, I uploaded the wrong file into RS6. I wanted to compare the DSD256 I found on native DSD against the same file upsampled using that program.
- I still prefer DXD compared to DSD on RS6. It appears the program does extreme filtering for the ultrasonic freq.
I'm using the free version and seriously considering buying this program. I had bad luck with its foobar version, which is the lite version of the same program.
Conclusion:
Overall, I couldn't recommend this DAP enough. I understand now why MQA sound so good on RS6. For now, Hiby only OS MQA file, and other files appear to remain in NOS format.
I also hear the benefits of upsampling my favourite album to the maximum resolution RS6 support. The added benefit appears to be a better transit response that shines on classical music. The advantage becomes much more audible for live recording; the microdetail just stands out without ever being distracting.
Tonight I will compare PGGB with the free XiVero program and see whether the benefits I hear is because of the program or RS6.
Ther is a technical video on hibys weibo, I wish I understood it. Putting it here for those who might be able to translate it if they can.

Please see above,
I'm sure Hiby has enough power in this unit to offer frequency dependent, multiplication of bits up sampling in their normal settings menu. This would be a great FW recommendation from those reviewers that agree with you.
