You can check N7 prices.Of course, they are free to sell at the price they want, but other DAPs do not depreciate that much so quickly

Astell&Kern Launches New R-2R DAP and IEMs at High End Munich 2023
- Thread starter JasonNYC

Mine when connected at 5Ghz, I get same 54MB speed as you have in your screenshot, but if I connect at 2.4Ghz I will get the same speed.Good evening, this is my last post on this topic, here I summarized my thoughts (I won’t do it again)
Dear owners of the SE300, I ask for your help to figure out what is strange in my opinion (after all, it’s 2024) connecting the SE300 to a Wi-Fi wireless network.
Further point by point:
1) I won’t talk about playback quality, overall impression, etc., you can find all this in numerous reviews of this device. I listen mainly to Lossless and Hi-Res Lossless in Apple Music, headphones – Beyerdynamic Amiron Home and T1 Gen2 (depending on my mood). The sound impressions are excellent, otherwise I would write in a slightly different tone. But, as always, there is one nuance that you will not find in the reviews. I'm a network engineer by profession, so let's talk about how the SE300 connects to your/our wireless network.
2) Immediately after purchasing the device, I naturally tried to connect it to my Wi-Fi network (I have separate SSIDs for 2.4 GHz and 5 GHz). The device was unable to connect to the network in the 2.4 GHz band; it only connected to the SSID in the 5 GHz band (this is preferable). Initially, I did not attach any importance to this, but later, due to the slow speed of Wi-Fi, I became interested in why the SE300 itself could not connect to the SSID in the 2.4 GHz band and why was everything so relatively slow? In the SSID settings for 2.4 GHz on the home Wi-Fi router it was “802.11n only”, changed it to “802.11g/n mixed” - the SE300 connected to the network. That is, the connection occurs in the 802.11g standard (Wi-Fi 3). Let me remind you that the maximum channel connection speed (Data Rates) in this standard is 54 Mbps. The suspicion immediately crept in that not everything was clean with the connection in the 5 GHz range. Unfortunately, the capabilities of the home router do not allow for detailed diagnostics; to do this, I connected the SE300 to the corporate network to make sure what standard the connection was using. My suspicions were justified - the SE300 does connect to Wi-Fi in the 2.4 GHz band in accordance with the 802.11g standard (Wi-Fi 3), in the 5 GHz band in accordance with the 802.11a standard (Wi-Fi 2). Let me remind you once again that the maximum channel connection speed (Data Rates) in these standards is 54 Mbps!
3) The actual data transfer rate will be approximately 2-3 times lower than the channel speed; in 802.11a/g standards, the maximum achievable actual transfer speed is approximately 20 Mbps (under ideal conditions). Basically, according to this article How Much Speed Do I Need to Stream Music? this is enough for streaming Hi-Res Lossless music. I specifically downloaded the track “Bad” Michael Jackson from Apple Music (103.3 MB) on the SE300 and it took about 40 seconds, 103.3 MB multiplied by 8 = 826.4 Mb divided by 40 (download time) ~ 20.66 Mbps.
4) The specification listed on the website astellnkern.com states that the Wi-Fi standard of the SE300 is 802.11a/b/g/n/ac (2.4/5 GHz) aka Wi-Fi 5. In reality, the connection occurs in accordance with the standards 802.11a (Wi-Fi 2) - the year the standard was adopted in 1999 and 802.11g (Wi-Fi 3) - the year the standard was adopted in 2003. Let me remind you that the device was released in 2023. Where Astell&Kern unearthed a wireless chip with such characteristics is a mystery to me these days; I still hope for a software error or a deliberate reduction in capabilities at the software level.
5) I scrolled through the forums and found the only message from user SE300 about a similar problem - post from CharlyBrown
6) I decided to dig further and found messages from SE180 users, they also report that the maximum speed is 54 Mbps (I am sure that they report the Link Speed value, that is, the channel speed). The specification listed on the website astellnkern.com states that the SE180's Wi-Fi standard is 802.11b/g/n (2.4GHz) aka Wi-Fi 4. Of course, I cannot know the characteristics of the wireless chip and Wi-Fi routers of users (I doubt that they use a Wi-Fi router of the Wi-Fi 3 generation), but the maximum channel speed in the 802.11n standard is:
- 72 Mbps (20 Mhz, 1SS)
- 144 Mbps (20 Mhz, 2SS)
- 150 Mbps (40 Mhz, 1SS)
- 300 Mbps (40 Mhz, 2SS)
This means that the SE180 also connects to Wi-Fi in accordance with the 802.11g standard! I don’t want to make such a conclusion, but it turns out that this is not the first time that Astell&Kern “lies” (in quotes, because there may be problems with my device?) in a published specification?

7) And finally, and most importantly, dear owners of SE300 and SE180, check the channel speed of the Wi-Fi connection (Link Speed). Does it exceed 54 Mbps?
8) I just want to figure it out:
- there is a problem with my device due to the fact that it not genuine? Or defective?
- the problem is that someone is specifying the specification incorrectly
9) For streaming in Apple Music, the specified speed (20 Mbps) should theoretically be enough, I don’t know if Apple Music has tracks with 32-bit/192kHz (24-bit/192kHz is available), let’s take the maximum (for 32-bit/192kHz 12 Mbps required). But here you need to take into account that 20 Mbps is at a channel speed of 54 Mbps. Radio broadcasting is a constantly changing environment, both in time and space; you shouldn’t rely too much on “theory” in terms of actual connection speed. In real conditions of noise, interference, distance from the Wi-Fi router, interference in the form of walls between you and the router, your channel speed in 802.11a/g standards may be lower - 48, 36, 24 Mbps (I will not indicate speeds lower than 12) , accordingly, the real speed will be less than 20 Mbps.
20 Mbps in ideal conditions is enough, but playback does not start immediately due to track caching. This is annoying, there is a fairly large delay, if the speed met the specifications it would be faster.
Device - Roon Ready, is this speed enough to play DSD256 (for example) from a NAS?
If I want to save a track to a device with Apple Music, I’m not satisfied with this speed in 2024.
10) I am attaching screenshots when connecting to a corporate network, the second device is an iPhone. So, you can see for yourself that the SE300 connects in accordance with 802.11a/g, the iPhone (as indicated in the specification) in accordance with 802.11ax standard.
Seems that AK can do better here, this is probably the bottle neck affecting the speed of streaming apps.
This is a peaty, because SQ is awesome, but for the premium price, brand position as “futura” it operates in past… I’m not thinking of selling yet, but I’m getting more and more annoyed when using Qobuz or Tidal.
Hope that AK can fix this through future firmware updates.

I still hope for a software error or a deliberate reduction in capabilities at the software level, and not for hardware limitations.
Reducing capabilities at the software level is possible for less energy consumption, for example...
Exactly, I tried other DAPs with lower and similar specs and they were much more fluidThanks for your feedback.

I would say this due to FOMO.. some people nowadays just do not care about the price deprecation.. they just want to sell their device so some of them set a really low price so buyer will just grab it... N7 is quite an example...Of course I agree with everything you said, but let me remind you that SE300 has not been released 3 or 4 years ago but only 9 months ago. This does not make it obsolete in particular if we know that there aren't a lot of R2R DAPs in the market. I am not aware of new R2R DAPs recently released. What I don't understand are people selling their device at half the price after using it 6 months or even less. Of course, they are free to sell at the price they want, but other DAPs do not depreciate that much so quickly
Honestly, I typically let go at a reasonable price because I like giving folks opportunities to enjoy a device that they might not be able to at full price. Especially for a device I don't have much use for.I would say this due to FOMO.. some people nowadays just do not care about the price deprecation.. they just want to sell their device so some of them set a really low price so buyer will just grab it...

I would have the same thought but in reality reasonable is quite vague for some, some just like throw price...Honestly, I typically let go at a reasonable price because I like giving folks opportunities to enjoy a device that they might not be able to at full price.

Hi,
I received mine today and I'm very happy with it so far. It matches my hopes/expectations. Coming from the SP3k which was too heavy for everyday use for me, the SE300 is exactly right, 100% sweet spot. And it features the same beautiful UI as the SP3k, this is great!
There is one annoyance though, that only is a problem for the initial setup. Both Wifi bands only connect at very low speed. 54MBit/s for both 2.4Ghz and also 5Ghz even if I put the SE300 directly side by side to the access point.
Like this it takes ages to download my playlists from Apple Music, hundreds of Gigabytes.
All other devices connect with up to 1.2Gbit/s on 5Ghz and at least 75Mbit/s on 2.4Ghz. I don't remember having this issue with the SP3k with the exact same network. Is this a common problem with the SE300? @JasonNYC could you look into this, please?
you are still connecting at low link speed 54Mbps at all wireless band?

Hi,I left a message with the team in Korea. It is a holiday there (Memorial Day), I should have a response once they are back in the office.
you responded to post from CharlyBrown about low wireless link speed.
Please see my post.
Could you provide any new information about this issue?

Apologize for the delay in responding. I noted all of the posts and will share with the team members who are coming in for CanJam NYC this weekend. I may also follow up with a few individuals via PM for more info. I didn not see where everyone was from, but wondering if it was certain regions or all over. Also, has this recently happened after the last firmware update?
I am currently getting about 433 when connected via 5G on the SE300 I have here on the latest firmware

Sorry I can’t help. I returned the SE300 back then and changed back to the SP3K.Hi,
you are still connecting at low link speed 54Mbps at all wireless band?

I use the European version of software (CM). As far as I remember, I did upgrade three times in hopes of fixing the issue. I don't remember the original software release version, but I updated to 1.06CM, 1.11CM, 1.12CM. It was the same issue on all four versions.
I tried connecting to:
- home router
- corporate network
- network shared via iPhone
To no avail, I always connect at the 54 Mbps of the Link Speed. I will share the screenshot where I'll try connect to network from iPhone. Sometimes it's connect to 2,4Ghz, sometimes to 5Ghz.
p.s. I saw your screenshot and was upset, I hope I have a genuine and not broken device...
Anyway, thanks again for the quick feedback!

Thanks @JasonNYCI am in Hong Kong using CN version.
I'm based in Europe, Portugal, latest firmware... I have a Mesh network (2,4Ghz/5Ghz/6Ghz), no matter if I connect to 2.4Ghz or 5Ghz, very close or distant to the router I always get 54Mbps of link speed...
