Try to upsample PCM to DSD (256/512, whichever your DAC supports) and play through your DAC. Then compare it with your 16/88. Let us know how that goes.
My testing confirms 16/88 is the best sounding sample rate
Sam here and i just made a new discovery 16/88 is superior to any other sample rate as far as sound quality goes.l won't upload audio samples however you can easily run your own re-encode and prove me right.This will be my new format of choice.ls it a coincidence that the best sounding format is the one that is not offered as a hi-res choice? or or they trying to hide something from our ears.
