Quick check and Question on trascoding flac to WAV

[simoncn]

This depends on the DAC you are using to play the transcoded audio. Your Naim Muso supports 24-bit WAV but not 32-bit WAV, so you should get the best result on this device by transcoding to wav24. Your Naim Atom and Nova support 32-bit WAV, so it is possible that transcoding to wav32 might sound better on these devices than transcoding to wav24.

As DavidHB has said, the only way to be sure about what sounds best on your system is to try different settings and listen to the results. When doing this, it is often difficult to overcome "expectation bias" where you have a preconceived expectation about what will sound better and your brain subconsciously reinforces that expectation.
