Last night I filled an external hard drive up with all the music on my Grimm MU1 for use with my Pink Faun. Then I fired up the Pink Faun. I had logged off of Roon on the MU1 and logged in with the Pink Faun. It immediately updated to the latest version of Roon without incident. I hadn’t used the Pink Faun since September 2021.
I copied the Roon backup files and restored them to the PF. Of course when the restore was done it had hard drive settings for the Grimm. I pointed at the internal SSD and External Hard Drive. All my playlists said nothing available. When I woke up in the morning all my playlists were fine and had found the new locations of the tracks without issue. A nice surprise.
How does it sound using the PF as a server and the MU1 as an endpoint? It sounds wonderful!!
The MU1 still works it’s magic in the jitter removal and upsampling. It’s built in NUC isn’t doing anything when it is in endpoint mode I am guessing.
Does it sound better than letting the MU1 do everything? It just might. I need more time. I can switch back and forth fairly easily.
When I bought the PF I spent $2k on the upgrade USB board with two fancy and exotic clock chips in it. Tonight I’ll hook the Shunyata Sigma USB cable to the PF a plug the other end into the Gryphon Ethos to hear what there is to hear. The Sigma is currently hooked up to my MacBook Pro SSD which has not been used once since I returned to the Grimm. I hope the PF straight to the Ethos doesn’t sound too good. LOL.

Found a local hobbyist parting with several of these:
I am going to drive out and pick up a pair of these hinged panels tomorrow.
They are covered in a burgundy-colored fabric and I plan to experiment with them in the corners of the front wall as bass traps. They look like they have some flexibility as to how they can be deployed so I am hoping I can find a configuration that will have a positive impact.
Should be fun as the seller has the same model (newer version) of speakers I have and some killer components upstream of speakers that I am going to get a chance to listen to…

The flexibility of streaming for separating or combining endpoint, renderer, server, control, is brilliant innit

You might have to sell the MU1.

These 2.75" thick hinged panels from GIK were designed to be used in multiples to create impromptu vocal recording booths. Even used straddling a room corner they won’t make great bass traps- Too big an air gap vs too little porous absorption. To use them as effective bass traps you would need to hide some big bags of fiberglass pink stacked in the corners behind them.

Not according to the GIK product page…unless I misunderstood the copy:
“…when it’s unfolded it behaves like our 242 Acoustic Panel which makes it perfect as a vocal booth, around a drum kit or guitar amp, used in early reflection points of the room or help eliminate slap echo from side walls. When it’s folded it behaves like our 244 Bass Trap ideally straddling the corners or mounted on the front wall.”
I wish they were still a company worthy of dealing with. But they are not. They are not worthy of anymore business from me.
I understand you had some quality and customer service issues.
Fortunately, I get to inspect these in person. And, if they are in pristine shape like the owner says they are, I’ll be able to ensure they get home safely and in tact.

I’d like to try a set of those in between my listening area and furnace.

Yeah, @paul172; you should rip out all of your current HVAC system and reinstall a quieter system – all in the name of better sound.
Seems legit.

Like GIK’s general purpose 242 panel, the folding screens only use a 2" depth of porous absorptive fiber in them. The remainder of the 2.75" depth of the finished product will be a small air gap created by the surrounding wooden framing. Here is the Riverbank Labs absorption vs frequency data which GIK provides for their 242 panel.
GIK do not provide actual measurement data for the Folding Screens product you intend to purchase but as the frame is actually nearly an inch shallower than the 3.6" deep frame of a 242, I’d expect the Folding Screen’s low frequency absorption to begin rolling off even a little higher up. This is a product meant to be used as a recording tool to absorb sound reflections in the typical human vocal range. At less than 3" deep I wouldn’t even consider it to be a satisfactory broadband panel for sidewall reflections. For that you would need to look to GIK’s 5.25" deep 244 panel which sports 4" of porous absorption and a 1.25" air gap.
The first genuine bass trap in GIK’s line is the 7.3" deep Monster Bass Trap, particularly when you select the range limiter option. By the way, understanding the physics of how these traps work I expect that the the absorption measurements which GIK has provided for the Monster Bass Trap were with it straddling a room corner to create a much greater air gap. Placed flat to a wall I’d expect the low frequency absorption to begin rolling off an octave higher- at least with the standard non-Range Limiter version.

These will be appoximately 5.5 inches deep when folded – although there will not be much of an air gap provided by the folded panel itself.
I understand your point, but I am expecting these to be somewhat effective as “bass traps” if folded and placed in/across the corners of the front wall - straddling a room corner as you mentioned above. That’s how I intend to use them.
Thoughts…?
[Edit: I re-read your first post - and noted the point about the overall thickness being potentially insufficient. Too bad GIK does not post the measured performance to support its claims. For the price I will be paying, maybe I will add some appropriate materials to the space behind them when placed across the corners of the front wall.

If you are still set on purchasing the used GIK Folding Screens and are trying to achieve some useful bass absorption, then my earlier suggestion still stands. Use them mostly opened and straddling the corners behind your loudspeakers. Buy a bag of compressed R11 or R12 fluffy fiberglass insulation at your local builders store and and at least a half dozen cheap zippered pillow cases. Lightly stuff the pillow cases with the fiberglass insulation and then stack the stuffed pillow cases in the corners behind your panels. That will get you useful bass absorption down into the 50-60Hz territory along with a finished appearance.
