Pigtronix Infinity owners, noise issues?

[cloudsabove]

Hey you Pigtronix Infinity owners, do your units add noise?
I have to say that I love this looper, it's the best by far, but mine is unusable at stage volume because it adds a lot of hiss.
The hiss is audible only when I am playing at stage volume and it increases as I turn up the presence on my amps. To reduce the noise I put a clean boost in front of the Infinity and keep the volume of the Infinity way below unity gain. This minimizes the noise but do not solve the problem.
This happens with different amps, different cables, guitars, power adapters, sockets... and it is the same in my home and in my reharsal room.
I agree that white noise is common with digital effects, but this is a loud noise that I would expect only when I set the pedal for a gain boost, not below unity gain. I have the same noise with the tape saturation side of my Strymon Deco, but the noise starts to appear only when I am way over unity gain.
When I emailed Pigtronix about this issue, it wasn't clear if my unit was faulty or if it was the common behaviour of the pedal.

In front of the amps. I have a JTM45 and an AC30, no efx loops. The white noise is present even plugging the guitar into a mixer and a couple of monitors.
I tried the pedal alone and in the pedal chain, tried different cables and power adapters, but it's always the same.

How old is it? The chip craps out eventually. I think Ugly Nora is on his third one.

Really???
S/N is 4813, I bought it new from Thomann two months ago.

Well I have 3 but only 1 of them seems to be malfunctioning (that's why I bought the 3rd one because I wanted to have 2 functioning ones). But also, for some reason, I have issues with the oldest 2 being able to update properly (haven't tried to update the newest one but I shouldn't need to anyway). It always tells me the device is not connected which it obviously is because I can browse the files on the looper when connected to my computer. I don't know if that is a computer issue or what. I need to contact Pigtronix about that. The broken one is s/n 1186.

I have never had any noise issues, but I don't play stage volumes.
