[ask] sound quality worse than the original firmware ?

[Paleskin]

Hi guys, I have sansa fuze and sansa clip plus, both are rockboxed, but the results :

Sansa clip plus ---> rockbox makes the sound quality higher, more warmer

Sansa fuze ----> rockbox makes the sound quality lower, more bright, less warm

How to fix this, so rockboxed fuze have warmer sound like the clip plus one ?



Thanks

People have done RMAA tests comparing both firmwares and they're identical. You can double check that theres nothing weird with your player in RMAA if you want, but its probably just your imagination.

@OP: yeah people totally hear stuff differently. But, not to me in these examples and enough people have discerned no difference that its likely the case.

You can do a simple experiment perhaps. Try your best to volume match the 2 devices for a specific song. Use the same headphones, FLAT EQ under RB and original. Get a friend to help you and don't look [teach friend how to use RB and how to reboot into original FW]. Listen to song without knowing if RB or original FW.

Simple, not really 100% definitive, but a basic blind taste test thing...


Then buy your friend a beer to celebrate that RB and original FW sound exactly the same with no EQ.

Are you listening at the same SPL level using the same head/ear phone?

I have always used my Fuze V1 Rockboxed. But, recently, I uninstalled RB, used it for a while and then re-installed RB. To my ears, there's no difference across the three instances (and yes! I used the same IEM).

@Saratoga, @lestatar, @Esantosh, I already did the blind test with my friend
- matched the volume using my ear
- same IEM (yuin pk3)
- flat eq
- same spesific flac song

I can easily tell whether the one I'm listening to, is the rockbox one or the OF one, just by hearing the playback

The rockbox one sounds too dry (bright for some ppl), while the OF is warmer

No,I didn't do any RMAA tests, because I used rockbox automatic installer, so I assumed what I got is the latest stable build

And no, I don't use any portable amp at all, it just a dap and earphone setup, nothing more

Hmmm, interesting...what can I say? You went to the trouble to try stuff and came up with results most wouldn't so for sure, props to you.

Still, not sure what to suggest at this point - you may indeed have extremely exceptional hearing to discern differences between RB and original Fuze FW. Maybe some quirky hardware thing somehow? Maybe saratoga might have some more input?

Maybe gremlins?

<I'd still buy that beer for my friend though...>

I can't add anything if you took the ABX and still was able to detect changes. Like Les said, you may have better hearing range and ability to differentiate than I do. I can uninstall RB in one of Clip+'s and try. But, even in an open-eye test, my bet is still on detecting 'no changes'.

My friend today said exactly the opposite (No ABX done in his case though) that after installing RB, his Clip+ became much more "sterile" from warm. I guess saratoga owes us all an explanation for changing the signature of the different players differently

Run the RMAA tests and post the results and I'll take a look at them.

@saratoga, I just need too connect my fuze to the mic line, using interconnect cable, and run rmaa, klik just recording, then start test, right ?

And I must run both for OF and Rockbox, right ?

And the config is just like this ?
