Here is my first class D amplifier made with following Connexelectronic modules:
2 x IRS2092 Modular Amplifiers 600W 4Ω. each and around 900W 8Ω in BTL mode.
1 x Balanced Input Phase Shifter to select symmetric / asymmetric and stereo / BTL modes
1 x SMPS2000R power supply. 80V 2000W.
I received these modules completed and tested. I simply mounted them in a 2U chassis, added some wires, 2 fans and few components...
The result is a very stable and nice sounding amplifier in stereo mode as well as in "bridged" (BTL) mode. It sounds GREAT, with powerful and strong bass, while keeping details of medium and high frequencies and without any white noise, hiss or 50Hz noise.
When I compare with a Class AB power amp, I cannot say which is better than the other.
I regret having received the modules without any documentation and specifications. Fortunately, the silkscreen printing on PCB allow do without.
Very well designed modules, with excellent construction quality and good value for money. Highly recommended!

nice looking amp!

I've got a ta3020v4 board but this looks like it would fend better in a PA situation with the larger 2000w supply.

This is my test setup for the 3020 amp in balanced configuration. Both channels are powered by a 1200W power supply.
The power and control of this setup is enormous. It equals my version of the X600 amps.

I found ConnexElectronic during my search for a high-power, hi-quality audio SMPS solution available to the public in small quantities for some amps I was building as part of a larger ambitious R&D project. In the process, I made acquaintance with Cristi, which quickly grew into a transcontinental friendship. I have learned great respect for his hard work, skills with electronics and willingness to be forthright and earnest. I really like these power supplies. The Connex supplies are very robust designs that can easily be customized to suit nearly any audio power supply application - frankly for a bargain price. The soft-switching resonant LLC topology (among some of the others available) allows for very efficient, compact, noise-free amplifiers.

I built two multi-channel amplifiers, an 8 channel UcD400 and a 16 channel UcD180LP. Both use a SMPS2000R supply. The 8 channel is for a home theater system and the 16 channel is for a distributed audio system. These are prototype amplifiers. Higher power SMPS will be used in the future - as they become available. Coming soon are multi-channel UcD700 and UcD2k amps.

The Hypex UcD technology has also become a favorite of mine. Specifically, UcD technology is truly elegant in design and it has become the standard I judge amplifier performance by.

I'm thrilled with the performance of these amps. Quiet, clean, efficient, powerful and accurate. I implemented a bottom-to-top forced cooling method that works well for the application they are being used for. The aluminum cases were machined, drilled and etched by my home-built CNC. Each channel has a green/red bi-color LED channel mute/enable button that monitors channel power supply errors and a volume knob with a green/red bi-color LED built in for channel signal detection and clipping.

I built a pair of Tripath 300w @ 4ohms using an SMPS500R in each mono block.

finally got some pictures on my TA3020v4 board mounted in its very unassuming case its mainly a test fit so far.

Originally got the 8x8 amp for the case to build a stereo lm3886 amplifier, which it was for a number of years but the board design had a bad hum problem so I decided to put this board in it.

I do have a problem with air flow, being there is no air flow with the lid on so I'd been testing it with the lid off.

So I'm wondering what the best air path would be so I could add vents and a fan.

hypex ucd700hg-hxr with smps1200a and salas 1.0 input stage.

at the picture is one channel because they are monoblocks.

they sound awesome.

@SeduceMedusa :

Wow!

This is the most insanely stuffed amp installation I have seen so far! Keep it up!

Greets,
