Yes I understand that but you replied to KupingManja and he is experiencing the problem mostly when he connects his SP3K by Bluetooth to whatever transducer he is using. So this sounds more like a Bluetooth issue and 192Khz files than anything to do with the SP3K. But it’s nice to know that the SP3K has no playback issues with pggb files. I’m presuming you use multiple 1Tb or 2Tb SD cards? A&K do warn about repeated mounting and dis-mounting of memory cards but again I’m guessing you haven’t experienced any issues so far?
My bad… didn’t read far enough back. I rotate three 1.5gb cards.

I use three 1.5TB cards with my SP3000. To avoid repeated mounting, I use a USB-C Micro SD card reader for two cards, with another left permanently in the SP3000. I have done repeated testing, and there is no difference in sound quality.

Good idea!

With what device do you have the Bluetooth connection and does the file play perfectly when you listen to phones/IEMs connected by wire?
It doesn't matter which transducer I used, tested with all 3 different equipment, same problem.
Tried to move the files to internal storage of sp3k thinking maybe it will read faster than the microsd, but nope problem still the same.
But when I use the physical port for LO or PO, problem is not happening.

Definitely sounds like a Bluetooth bandwidth limitation issue as you are not having the issue when connected via wired. Could you provide some additional info such as what codec you are using and what Bluetooth products? You can PM me if you prefer.

Any chance of integrating Qobuz like we have Tidal? Hiby integrates more than one streaming service into its player. Yes. I could just download the app, but it can be a lot slower.

Especially on the sp2000. Qobuz can just freeze these days.

Can you explain what you mean please? I use Qobuz all the time on my SP3000 both in online and offline modes and I don’t experience any problems. SP3000 is much faster than SP2000, I have both.

I believe he prefers if the Qobuz app was integrated like the Tidal app is.

Recently bought an SP3000 copper with the A&K Pathfinder special offer. Love both but looking for some help...

1/ I ran a SanDisk 1TB SD card with my old SP1000 without issues. Put it straight in the SP3000, worked for a while, but then boot looped. Formatted the card inside the SP3000, reloaded FLACs and after a few days boot looping again. I've added a few FLACs to the card since - any ideas?

2/ I run the A&K Pathfinders via the 4.4mm connection. I'm convinced that I'm getting some kind of voltage leak from them as I get a live tingling sensation in my ears? Am I crazy? Doesn't happen with my Sennheiser HD800S connected. I'm normally using an Apple MacBook Air M2 when it happens. Is there some kind of weird grounding going on? (Now I feel like I'm rambling like I'm crazy)

Yea I have 30 cards all play on my sp2000, only 5 play on my sp3000, tried formatting new cards on the sp3000 and transferring the files to them but wouldn't play on the sp2000 or sp3000. Seems the card reader on the sp3000 is more file sensitive than the sp2000 , sp1000 .

I format cards on Mac first FAT32 seems to work fine.
