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.

^^^ very nice build also. Looks very professional.
Thanks guys,Prasi are you sure that you want to see my bench?Very nice build my Greek friend. Very very professional...

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.

Interesting thimios, but this is not a simulation. The XPA-150 has been a production product since 2013 and the first version was released in 1996. If it were so wayward, I would be hearing about it by now.
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

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.

Perfect example of a horrible practice
