Very nice build my Greek friend. Very very professional...
Does this mean you will stop with your"hardcore DIY-Home etched PCBs- with lots of Solder over tracks-with a cluttered bench in the background", that we are accustomed to see all over DIYA😀?
It should almost feel like the best and ultimate builds for yourself... Sure looks like it to me.

Thanks guys,Prasi are you sure that you want to see my bench?😱
Never,i will continue the diy pcb when i haven't a better solution!
All stuff melted together, up and running. Stereo amp + log VU meter + headphone module + input selector + ak4490 DAC + tube PSU + soft start + DC blocker + 30% free space in enclosure.
Couldn't resist and made quick 4L box for PS95 - small speaker with big sound.
Regards

LC, thimios
Thanks for kind words !!

Input selector controller is simple 4 position rotary switch (but can be raplaced with some remote controll too).
Nice dual mono setup there, Plenty work with enclosure, like it a lot.

SA2015 slew rate > 100Vus
power bandwith limited by RF input filter.
More details here:
2stageEF high performance class AB power amp / 200W8R / 400W4R

Interesting but i am not falling for that ....
If this is not diy but a a commercial product than is going to be hard to discuss this here ....Obviously there is too much protection around it
I can share my opinion in details but probably this will require a dedicated thread for it ....
Kindest regards

It's a joke of course 🙂 Input filter 1st order with R-470ohm and C-220pF can not degrade rise time from 100V/us to 21V/us.
If you want discuss SA2015 then this may be the wrong thread.
Where have I said, that the RF input filter reduces the slew rate?
Thimios measurement was from a small signal 20kHz output with 8Vpp after pi zobel filter.
Have a look at my "2stageEF..." thread post #1386. Measured after pi zobel 8R load fullpower with all protection features in situ.

A little one.
I do not bridge the caps with little ones or different caps. I set they at "ONE point"-)
I regard circuits😎
I do use Shottkys;-!!!
A result than:
Just 3 pieces to form a "perfect amp".-PPP
... not finished at moment.

ESP Phono Preamp
ESP project 06 Hi-Fi Phono Preamp plus project 05C Power Supply for Preamplifiers. My construction is not going to win any beauty contests for sure but sounds good to me.
