Some thoughts. Take from them what you will.
from Jussi (HQPLAYER):
"For some comparison, on my home/office WiFi network based on two HPE 802.11ac AP’s I can do 8 channels of DSD256 from my Lenovo ThinkPad laptop connected to WiFi, to HQPlayer NAA (on Ethernet side).
That is about 86 Mbps constant"
would have been nice if CHORD had a wireless expert at the same level as Watts on DAC design. Use your brother in laws dev shop in the philippines and this is what you get.
There has been a lot of jumping around in the discussion between topics, which I think is confusing. I'm using Roon to the 2go/Hugo 2 and even over Ethernet, there seems to be the occasional clicking and popping. I'm going to test with the new firmware to see if it has improved. I'll include 192k music.
Of resolution, I wouldn't bother trying to deal with music above 192k or DSD128. Given even a lot of 192k music has a lot of ADC noise in the higher frequencies (depending on the ADC used) you're fussing over inaudible noise. 48, 88.2 or 96k is arguably more sane.
I don't know what system Jussi uses to run NAA, but his test is between a ThinkPad and a full-sized router. The 2go is not a full-sized router. The results I get over wireless with the 2go, are better than if I set up a Raspberry Pi and its in-built wifi, which can barely even stay connected to a wireless router a few meters away, let alone stream music.
The question about the built-in wifi only having one channel has me asking more questions, and not assuming simply that it should have more channels or 5Ghz, as we don't know what trade-offs,
if any, were made so that 2go would be able to fit into a small box and have sufficient battery life, and which were unnecessary to get reliable streaming. Armchair speculation about chips is just silly.
That all being said, Wi-Fi is a load of crap at best. I have always taken the time to lay out physical ethernet connections for all the computers and other devices I use, where possible, so as to avoid it. I'm lucky in that I live in a house with only a few neighbours around that have wi-fi, and I, being more technologically aware than them, bought a multi-channel router, and also have an older Apple Time Machine which I've carefully placed on non-conflicting channels. I reckon that if you live in an apartment and you're seeing a dozen or more routers from your computer's wifi panel, then you most definitely need to be more proactive in avoiding using wi-fi on the 2go.
Lastly, if it is driving you insane, send the thing back.
