Measurements of Topping DX3Pro LDAC/V2

Got it working can play at DSD256 12.288Mhz now on new system. Previous system refused to play 48k DSD for some reason even though using the same driver.

DX3Pro cannot switch from DSD256 (11.2896Mhz) to 12.288Mhz correctly - plays too slow in this case. Only way to get the DAC to sync correctly is to change to a PCM output mode, then back to DSD256 12.288Mhz. Same when going from DSD256 12.288Mhz to DSD256 11.2896Mhz

What software do you use? I once had this error on Foobar. Switching the output from dsd to psm and back fixed this bug. I don't know if this is a Foobar error, a Foobar component error or an asio driver error.

Use HQPlayer with sinc-s filter that can only upsample to integer multiples hence 44.1k source to DSD256 11.2896Mhz and 96k PCM source to DSD 256 12.288Mhz. Interesting the DX3 Pro display shows 22.5Mhz rather than 11.2 for 48k DSD256.

DSD is standardized based on 44.1kHz and there is no DSD based on 48kHz. So, technically, I think that even if it is possible to convert from 48kHz to DSD 256/12.288MHz, the DAC side is not made assuming such operation.
