@Fosi Audio, any plans to offer these as a bare amp board/module down the road?!
Almost right on cue, my son was playing music this afternoon and the speaker outputs on the Parasound integrated cut out and won’t come back on. Wish this had happened a little closer to the delivery of the mono blocks, but at least I know I have a solution on the way if I can’t get this thing going again. Failing that, it’s back to my crummy Yamaha AVR for awhile.I bit on the Kickstarter earlier today, and got the 2 amp + 10A power supply bundle for 27% off. I’m curious if I’ll notice much difference vs. the Class D Pascal amp in my Parasound NewClassic 200 Integrated. I was kicking around the idea of getting a Hypex amp but this seemed to make sense for my set up and is certainly more budget-friendly.

Sorry, we currently do not have a plan to offer amp boards or modules of the V3 mono in the short term, but we are indeed looking into this business.@Fosi Audio, any plans to offer these as a bare amp board/module down the road?!
We're looking forward to your sharing of comparing the two setups.I’m curious if I’ll notice much difference vs. the Class D Pascal amp in my Parasound NewClassic 200 Integrated.
It feels like you're on the same wavelength as us! We've recently begun exploring a similar solution – housing multiple amplifier boards within a single chassis and incorporating an internal power supply. Users will have the option to install anywhere from 2 to 5 amplifier boards, somewhat akin to a NAS system supporting multiple hard drives.Have you considered putting two of these amps into a single, 1U rack-mountable chassis?
One set of switches instead of two, most probably better cooling and if the PSU was in the same chassis, a MUCH tidier setup.
Yes, we'll provide a Y splitter cable for the connection. Probably we'll also provide an external power filter.I'm assuming there is some special cable to link both amp to the same PSU or are we dealing with a PSU that has two output connectors?

Strange to think how may this be possible that they didn’t find it in their product before sending it to so called youtube influencers.
He has some problems with the 48v / 10A powersupply. He recommends having 2 independent instead

What happened to internal testing and all!
Do the y-splitter cables come with the 4x amp, 2x power supply backer option or do I have to add them as an extra?It feels like you're on the same wavelength as us!

My SONY cassiever in the eighties would let you set the backlight from green to orange to white to match the cockpit lighting of your car. ;-)Add BLUE back-lit VU meters and we have a winner![]()
When a device is pre production it is because the development is not finished. More often than not the product testing is still ongoing. It would be a surprise if pre production devices didn’t have some issues.Strange to think how may this be possible that they didn’t find it in their product before sending it to so called youtube influencers.

Edit: I missed that he has posted a pinned comment, Fosi had already responded to this:
"Hi everyone, regarding my power supply issue, Fosi reached out to me with the following note: "We sent you a 48V/10A power supply along with a power splitter cable. However, as this is from the first batch of products, there is a noise issue when using the 48V/10A power supply with two units. We are currently working on solving this issue, and the officially sold products will not have this problem. Please be aware.""
The power supply sharing is something interesting to me. Actually, various TPA3255 can be operated in master/slave mode so that they delay the switching between each other, apparently to "minimize noise coupling between audio channels through the power supply." and "Inter-channel delay is needed to optimize audio performance and to get better operating conditions for the power supply" according to the datasheet (below).
Given the fact that most probably two fosi sharing PSU with one of these Y cables are in fact directly connected in between, but not in master/slave mode, i would be curious to understand what this means for the performance of the amps and the power supply.

I don't see any mention to radio stations whatsoever, only to issues related to power supplies and noise. If you are referring to the choice of a different switching frequency to avoid radio interferences is a completely different thing.
