@gstew It’s powering RPI #2 (player connected to Dac). The most immediate positive sonic improvement was the Bass becoming fuller & tighter, never heard before sounds popping out of my reference albums :). I still need to spend more time listening to it & give a confirmation. But yeah in brief, what I mentioned above definitely is a step up. True, our systems are topologically similar. I’ve been eyeing the Soekris 1941 DAM (Balanced), not sure if it does i2s.

@gstew Greg, the whole troubleshooting gig was thanks to Alex C. Let’s just say, I’m no slouch with HW :)

Gents, I’m happy to confirm that the LPS 1.2 is successfully powering a RPI4. Been playing music for an hour without any hiccups. FYI, I’m running a Server and Player setup, RPI #1 server (4TB Music HDD) running LMS & RPI #2 Player (connected to Dac) running Picoreplayer, Squeezelite if you will. Its possible due to the OS being very lean it’s not overloading the LPS 1.2. YMMV.

Hi Greg, I purchased a “used” IR in Oct 21, but only managed to try hookin it up last month Aug 22. I have a Denafrips Ares II Dac & RPI4 (picoreplayer OS). The IR is unable to do a “handshake”, in fact tried out several tests to conclude the health of this unit but the results were not positive. a) Removing the LPS-1.2 from the chain and powering the ISO REGEN directly from the UpTone-branded 36W AC>DC power adapter brick (normally used to “energize”/charge the LPS-1.2 unit). b) Putting the red switch of the ISO REGEN into the up (‘ON’) position. c) A different USB cable from the RPI4 streamer to the input of the ISO REGEN. d) Also tried using USPCB A>B Adapter from the ISO REGEN into the Denafrips Ares II DAC, with its tiny VBUS switch still in the “ON”position. e) Finally, On a Macbook pro I plugged in an USB thumb drive into the IR's output, with & without the USPCB (see attached pic). The IR is still unable to mount the drive. FWIW, The thumb drive has a red led indicator as you can see in the pics, which lights up when its installed correctly. I had to fiddle a bit with the IR's output to get that red indicator light up, yet no luck mounting the thumb drive.

Need some suggestions where I could use the LPS 1.2 (I have one unit which is redundant), was looking forward to pair it with the ISO Regen but Alex says my unit has malfunctioned :( Anyone powering a Raspberry Pi4 with the LPS 1.2?

Hey Bob, I have a Denafrips Ares II Dac (USB), what should be my Squeezelite settings for (audio output), (output settings) etc to setup my dac and finally have music :)?

I did fill the country code as “IN” & also given a SSID password, does it need to be the same password that my router has been set with or a new one? I’m wondering, since I followed the links & settings given in your thread which encouraged wired Ethernet connection. Should I just wipe the slate (SDXC card) clean & start from scratch?

@bobfa @audiobomber Guys, I tried installing WiFi but for some reason it didn’t work. This was just a quick attempt as I was in a hurry. Pls see the attached pic, “WiFi information” “ IP missing” What am I missing out?

Bob, any specific reason why you shifted from wired Ethernet cables to WiFi? Which brings me to an important question, I have to connect the (client) RPI4 to the dac, For which I will have to drag a wire all thru the room, walls, door frame etc. I would like to avoid doing this (Ethernet wiring over walls). Is it possible to use some kind of Ethernet extender? Like a Dlink Dir 505?

Can I use this cable https://www.ghentaudio.com/part/dc-gac4.html to pair the IR with LPS 1.2?

What are the basic settings everyone's using on Lxqt? I have 15. SET realtime priority to extreme 21. SET Cpu governor.... ( set to Intel pstate as my MBP has a 2.9ghz Intel core i7 cpu) Also In "option 4. Realtime expert config" what is everyone using?

Thanks @AnotherSpin and @bobfafor replying, that would be very helpful Bob looking forward to it. Btw, Piero was able to troubleshoot the problem e.g. the original file was audiolinux_350.img not audiolinux_350.img.gz, this is because unfortunately mac had decompressed the file after downloading it. In any case, the latest versions of headless 1.5.0 and lxqt 3.6.0 are to be released today, so I might as well wait a few hrs & get those.

I tried, Piero sent me that link yesterday. But somehow I’m dragging my feet on the first step itself :(.. I’ve done it before on the early AL 220.img file successfully but being away for 8-9 months I seem to be doing something wrong... I need to get the first step right and then everything will fall into place or so I believe (fings crossed

Returning After an 8 month hiatus from everything audio, I have downloaded the latest links (headless & lxqt) from Piero but I'm struggling to copy it on the USB stick. If anyone's posted a link on how to do this (Mac specific) please point me towards it. Anyone have success copying the img with Etcher? I use a Mac book pro as a server and plan on using the Celeron NuC as headless endpoint.

A very refreshing article and photos, Thanks for sharing Chris, Luv it.
