New TOL A&K DAP : the AK Ultima SP1000

Someone tested BAL output has 45mw per channel with impedance 32 ohm.

I was curious about the Current (Amperage) output, not the total power represented in mW.

Do you have a link where you got this info? Using a rough calculation of P=V^2 / R, with 3.9Vrms and 32ohm load you get 475mW of power.

Did anyone try the sp1000m with u18 tzar, is there an impedance mismatch issue?

I use U18t with bal out of SPKM (1ohm) and the sound is ok. 2ohm SE output of SPKM is OK too, there I use U18t with 3.5mm adopter. In general, U18t is OK with outputs up to 2ohm, but going higher will cause issues. I covered that in my recent review of l&p L6 where se 2.2ohm output was OK, but bal 4.4ohm messed up the sound.

Hi,

since the last 1.10CM update I'm not able to sync the Playlist the way I did before...
I can't find or browse Playlists anymore on the SP1000.
I Know there was a bug on the previous firmware with the default Playlists folder but at the end it was working OK with another folder.
Any help would be appreciated.

Edit:
The copied M3U file from Windows 10 to Internal Storage Playlists folder is 0 bytes.
But When copied to YYZZ folder ( on SP1000) the file size is OK... Then i have to move the file to Playlists folder so i can browse the PL on the SP1000.

I noticed Playlists located on External storage (MicroSD card) have to be moved to Internal Storage to appear on the SP1000...

Not working at all

I would agree if you feel the size doesn't matter there is absolutely no reason to buy SPKM but as for me the size/weight does matter so I purchased it
and am glad I did. I quite enjoy the organic low-end (bass) of SPKM...smooth and has full of life.

My unit seems to be constantly resetting itself when in line-out mode. Mostly when changing the volume or changing track. If I leave it playing it seems okay. Anyone got an ideas? It's upgraded to the latest firmware...

Is there a report about a batery measure problem since the 1.10 firmware? Is strange...for exemple i ear for an hour or more and the batery goes from 100 to 98% them i turn it off and in the next day when i turn it on the batery is on 90 or 85% that never happened before....

Hi,

Is there an issue with Playlists ?


I'm having trouble using the playlist file the way I did before the firmware update.

Before:

I was able to copy the playlist "M3U" files from my Windows 10 PC to the SP1000 into a custom folder named "Plists" located on Internal and External memory (It was working well)

Now :

The custom folder "Plists" is not working anymore.
The default "Playlists" folder located on External memory is not working anymore, I can't browser files on my SP1000

When I copy the M3U files from my PC directly to defaut "Playlists" folder (Int Mem) it ends with a 0 bytes files but I can see the list name (with 0 song) on the SP1000
When I copy the M3U files from my PC directly to a custom folder name "Plists" (Int Mem) the file size is OK but i can't browse the list on the SP1000

From the SP1000, I need to move or copy from the "Plists" files to the default "Playlists" to have it working again and the file size is OK and I can play it on the SP1000.

I noticed the M3u files with music located on SD card can be move on Internal memory and play well... (It was not the case before the update)
Big M3U files copy hang.
