Did both on DMP and loade from PC before I left for work!Do remember to format the microSDs using your Walkman first.

No doubt that the Swissbit costs about 2x more than regular consumer microsd cards, but you have to consider that industrial microsds like the Swissbit comes with advanced error correction system designed for mission critical applications like in Banking, Medical and Military Applications where Bit Errors or Data Transmission Delay issues is totally unacceptable, as it can be the difference between life or death situation. And in our audiophile application, we would also want our music data bits stored inside the microsd card to be transmitted to our dacs/dap in absolute "bit perfect" & timing perfect conditions as well.Thanks.
I'm tempted to try Swissbit.
Please do compare with the M2 internal memory as well.Did both on DMP and loade from PC before I left for work!

The Swissbit is equipped with a more powerful 120 bit LDPC Error Correction Algorithm which allows it to detect and correct multi-bit error. The consumer grade microsd either doesn't have ECC or doesn't use as powerful algorithms.

Yeah, I usually compare directly to onboard and take notes, it makes comparison a lot better IMO depending on the load time / time to swap cards.Please do compare with the M2 internal memory as well.
Swissbit S-55U is limited to 256GB. It is using a Micron 3D TLC nand die.Yeah, I usually compare directly to onboard and take notes, it makes comparison a lot better IMO depending on the load time / time to swap cards.
Swissbit looks like it’s limited to 128GB?
Both the I and E cost almost the same. I went for the I version since it has the lower minimum operating temperature. Not sure if there is any technical difference between them.I also believe in microSD cards affecting sound quality. Years ago I was able to blindly compare my Sandisk Ultra to a Samsung Evo Plus - and the Evo Plus wins in the blind test. The Ultra just sounded "rough". So if this Swissbit card can do better than the Evo Plus, I'm willing to try it as well.
What's part number would you recommend? I see 2 S-55u, one with an "I" other one "E" on the part number (only difference I can tell is the minimum operating temp).

From my understanding, you should set this setting to the max value and then let volume be controlled via the system (+ - button on the device). After setting that, the loudness between streaming applications and offline files played by the walkman application should be the same.Hello ducnsh,
No I haven't touched the "Media Volume", Could I ask how I should set this, say all the way to the right (i.e. "max"), or somewhere between the far right and far left, or I should set this whilst I'm listening to the streaming?
Appreciates your advice.
Thanks
My question is really about the media volume affects what stage of the E2E signal chain?Hello ducnsh,

It’s very simple. Software mixers does it by mathematically reducing the amplitude of original PCM data. It does not amplify signals, meaning at 100% software mixer volume, the pcm data is not mathematically altered. At 50% Software mixer volume, your 90db recorded sine wave is mathematically recalculated to 45db sine wave. So you should always set software mixers to 100% and use the hardware volume controls if it exist.My question is really about the media volume affects what stage of the E2E signal chain?
My guess is that this is a digital control of the incoming streaming signal strength prior to reaching the DSP and converter, if so then would turning up this media volume lead to an output to DSP reaching 0 dBFS? If so than the subsequent signal passing to the amp section may clip.
Is my understanding correct /makes any sense? or its just doesn't matter and one just can adjust the medium volume to whatever position to ones' liking and the resultant SQ will not suffer a bit?
See if someone like to enlighten me on this topic ..
TIA
