Great! Not sure whether you have been able to find this - the link to the purchase webpage:

https://shop.musicteck.com/collecti...oo-paw-s1-leather-case?variant=32276928135230

I ordered it in the early afternoon and they have already sent it out.

I phrased my post poorly, oops.

I inquired with Musicteck about the case when a member shared it here, since at the time (1+ week ago?) they didn’t carry it.

Not trying to take credit, of course! Just interesting timing

Does anyone know what the output impedance of the S1 is, please? I ask because my google sleuthing skills have failed me and I don't see this listed in any of the documentation. (I ask because I'm considering pairing it with an Andromeda).

Should be 32Ω for both 3.5 and 4.4 output.

32 ohms? That would be disastrous. No way it is that high.
It drives my LCD i4 surprisingly well, although it is still not powerful enough to fully drive the sony ier-z1r.

BTW, I read it somewhere (I think from their blog) that the reason behind this is the power supply. Since the S1 does not have its own power source and relies on either the laptop or phone to supply it, this actually allows the S1 to give pretty powerful output. This also means that it works better with laptops if you need to efficiently drive some IEMs.

The specs only mention output power/channel at 32 Ohms for single-ended and balanced output. That is different from saying the output impedance is 32 Ohms. Need to ask Lotoo about the actual output impedance numbers but that number shouldn’t be high at all. I’m guessing < 1 Ohm?

My apologies if I give the wrong answer; not good at telling the difference between these parameters. I talked with the people from Lotoo, and they said they will come back with an answer shortly.

Was just told by them that the S1 can certainly drive the Andromeda.

Thank you so much for inquiring for us, I very much appreciate it! The issue isn't the ability to drive the Andromeda; rather, it has to do with the Andro's impedance curve - sources below 1 ohm tend to have a much more prominent bass emphasis; a slightly higher output impedance, ca. 1-3 ohms, makes for a better balanced presentation.

Thanks again for looking into this, it's very kind of you.

That's crazy. I was just searching for this information not 2 hours ago. And it doesn't seem to be published anywhere. As was already pointed out, that 32 ohm reference was not the output impedance. Looking forward to finding the value.

While I'm here ... I have a question about the PAW S1 specifically with the DX220. I asked over in that forum -- no answer yet. Does anyone know if the DX220 can be run with no amp module plugged in so as to extend battery life if I'm using the S1 ?

ASIO4ALL V2 in foobar working nicely with PAW -S1 :gs1000smile:

Capture.JPG

Hi, do you mind advising how I can set up AISO4ALL in Foobar?
I have downloaded/installed AISO4ALL but dont see it in the Windows Device Manager. I checked the Playback Output under Foobar and dont see the AISO.
Do I need to install additional component from Foobar?

The S1 output states 44.1k even though I selected a 192k file. Any idea how I can set Foobar to run at the correct frequency.

Did anyone Neutron player with S1?
Thanks for your help in advance
