Hi,

I got my SP2000 recently - everything works well except wifi drops out constantly while streaming (Qobuz, Apple Music, etc) when the screen turns off. Wifi reconnects once press the side button. I tried to explicitly set wifi using 2.4 GHz or 5 GHz band, but the same issue remained.

I noticed that there are some posts about A&K SR25, SR15, Khan, etc reporting this wifi connecting issue, though less on SP2000. I understand SP2000 is equipped with the chip supporting 5GHz band in addition to 2.4 GHz. However, from my tests, 5GHz supporting seems to not help with the issue.

I wonder if this is a common issue for SP2000. Is there any way to solve it?

Thanks.

Are you on latest fw? I just purchased my sp2k and had no such issues with spotify

I do think wifi is the only real weakness of AK products. I find i really need to be close to my router for great reception on both 2.4 and 5.

Yes, seems like 1 cable goes to the 3.5mm. That‘s for grounding I guess? I wonder how this can be called grounding when nothing touches the ground. But then again, I am not so much into electrical engineering.

I can hear siginficant differences between different Headphones, IEMs, EQ Settings. I hear zero differences between cables, connectors, adapters. This is a great gift, nature gave to me as I don‘t need to waste money on the later

Pentaconn is a 5 wire connection (TRRRS) which includes a ground unlike the 4 wire 2.5 mm balanced (TRRS). The ground is not normally used for headphones but can be used for balanced line-out applications. These adaptors use the ground on the 3.5 mm for the Pentaconn ground connection.

Hi @Vitaly2017 ,

Thanks for your reply.

I'm really confused about where the issue comes from. FYI, I'm using the latest firmware, 1.26CM and SP2000 Onyx Black. Can I confirm a few more details with you? While you are streaming Spotify, do you leave your SP2000 aside without touch it and are you able to constantly streaming it without breaking off? It normally happens for me between 5~30 minutes, which was monitored through the control panel of the wifi in my home to see the connected devices. Btw, can you check if your SP2000 connect wifi via 2.4GHz or 5GHz though both of the bands experienced the same issue for me. Perhaps can you tell me the simplest case, does your sp2000 connect wifi if you leave it aside a moment without playing any music or doing anything?

By the way, all my other devices in my home connect to wifi without any issue and SP2000 is also able to connect wifi with full signal once connected. I would not think there is issue with wifi in my home.

What my current understanding is that SP2000 (as well as other A&K DAPs) would drop out of wifi regularly when there is no data exchanging and the screen is off, which is normally the case when streaming music - automatically download part of the music and suspend and continue, and eventually drops out. The goal of this behaviour is to extend battery life.

If this is how they design all A&K products, I wonder why some people do not experience this issue. If it is not, why then?

I tested pw audio adapters and it doesn't deliver the quality I consider that would make it usable adapter.

Moon audio and DD hifi are better options.

I use adapters only for convenience, never as my main daily driver.

And not many adapters have worthy fidelity....

I use DDhifi, excellent quality adapters

And as for degradation of sound quality I can honestly say I hear none of that. But I would never deny that it is possible.. And if you are one of those that can hear things like that I'm sorry about your curse of golden ears.

Look closer at the innards photo and see that there actually is a cable connected to the 3.5 ground pole. I wonder about the innards of the DD HiFi connector?

Honestly, it dose changed the sound and rather obvious. I think our Mr. Tiger Ear mentioned? It's not a neutral adaptor at all because of the wires you see in the picture.

OK, I'm not a SP2000 only, but SP1000... I'd chosen PW because the look and solid feel. And it fixed the contact issue on the 2.5mm of my SP1000.

Theoretically, 3.5mm as a signal ground at the sleeve. Connecting the sleeve of 4.4mm TRRRS to the sleeve 3.5mm TRS supposed to complete the required balanced circuit. However, it's useless for the 4.4mm connection without a proper shielded cable. Anyway, not even the Sony's wm1a/z connected the TRRRS sleeve to ground.

Wifi is one of the weak spots of this DAP. I am fortunate in my place I am in direct line for the most part without much interference so I have zero issues.

I'm fairly new to DAPs (SP2000 is my first one). What do you mean "I am in direct line"?

I will do test once I can. I do turn on the screen before it reaches the 30min mark he. Tough I never had this cut off in under 5 to 10mins... I always use the 5ghz band as its the fastest!

Also I use a lot of spotify offeline content and I did download everything threw the night as the wifi speed is slow to download.

But once done its solid there! One thing I saw is that if I reboot the dap while spotify is on it will lose all downloaded data.
So I close spotify first then turn off the device
But to be extra extra sure it will not lose it. Simply never turn off my dap.


I find the sp2000cu very good for noise. Its super clean and this is the reason why we have slow wifi to avoid all the interferences....
So better be slow than hearing it!

Try reset your router might help who know!

Try reset your router might help who know!

Agree, I have tried to reset my router but did not help.

By the way, does your SP2000 keep connecting to WiFi if you leave it aside without playing any music for a while? This might be a simpler test. For me, it is disconnected.

Thank you.

I bit technical but... have you check on the wifi channel you use?

I was having similar issue before and I need to change the wifi channel in my router.

Not a lot of obstructions in my apartment, ie. concrete walls as opposed to drywall. I am referring to things that might negatively affect the the Wifi signal. It is a known weak spot in AK DAP's. I haven't tried all of their DAPs, but the one's I have.

I do not explicitly select a channel, which is normally chosen by the router (BT smart hub). Can you please talk about it in detail how you solved it eventually? Thank you.

I see. Wifi signal is actually "excellent" when my sp2000 is connecting to it. There are no walls placed between the router and sp2000.

My sp2000 never disconnected from wifi always connected even if not used.
