Default IRAUDAMP17

I have been interested in finding a good amplifier in class D, and I have seen with interest the iraudamp designs.
I don't want a powerful amplifier, and I've noticed IRAUDAMP17. It has very good especificacones in distortion and efficiency.
But searching the web design of this model, I only have found the "reference design" board.
I have not found any IR4302 chip-based design.

Someone can give information about the quality of this design?
You can find some board than the "reference design"?

IR provide everything you need to build the amp right down to a pcb layout.

Class D amp design can be a mine field as it is fussy about pcb layout, decoupling etc etc

I have built a few irs2092 based amps and they sound very good.

If you aren't confident to build your own then there are numerous vendors selling 2092 based class d amps.

Thanks nigelwright.
I will not begin assembling the IRAUDAMP17. It's too complex for me.
But I was curious to find some commercial board with this chip.

And yes, I've seen some commercial boards with 2092, thanks

I bought several IRAUD-amps at sure-electronics. Affordable price, good quality, all worked out of the box.
