I suppose $30USD for just the PCB is high when you're talking $6 for completed amp boards. 🙂 I wasn't necessarily going for cheap, as much as the sound. And boy, was I pleasantly surprised. It blew my socks off! The most transparent sounding amp I've built. So, despite the overall cost (>$300 including enclosure), it's one of the better amps and first gainclone I've put together. But I have a drawer full of $10 amps too. 😀

Hello ,
one question , I want to design a board based on TPA3116 .
I am planing on using a smps power supply and I was wondering if its a good idea to add a PI filter or RC filter after the power input

I have a upgraded astron and a 24v smps that was debugged to 55mv ripple/noise. The smps sounds better
Because the 3116 performs better at higher voltages

Unless you use inefficient speakers and need the extra power 13.8v is a better choice as there's less distortion.
In 2013, using the ampboards available from china then I believe in this thread it was found that above ~21V treble became more stressed than below 21V. Many people stil buy the amboards that were available then, meaning for them it is probably still valid.
Made my first TPA3116 PCB today, very do-able on 1 layer.
1SPW/PBTL/FB filter.
What purpose does the 3.3R/.1uF filter from pvdd to ground serve by the way?
An externally hosted image should be here but it was not working when we last tested it.

+1 On the dual chip board @ 100WPC off EBAY. I purchased one to try, and I liked it so much, I ordered another for my patio speakers. No MODS! I used it right out of the box with a SMAKIN 24VDC 5A computer brick off Amazon. Only have $28.00 and change invested in the whole rig, plus plywood scraps from my speaker builds for the box.

Here's my first dual chip mounted to a $25 Pyramid PS-3KS regulated. I just ordered an Astron SL-15R which I plan to use with another dual chip 3116.
I have a more powerful Meanwell but prefer the Pyramid.
I have a still nice sounding MUSE M50.
Any ideas for some possible upgrades? I realize now that is a dual chip also...

Chinese Koshin electrolytics have same topvent shape as Elna, but for RJH in Muse even that seemed too much trouble. You like the Muse?
Hope this one is fixed:
