Great review with measurements!

Ahhh... You're right, I accidentally mixed up a different frequency, my mistake... My intent was to show the difference in square wave leading edges.

Hi great video, but in the square wave test, I see that the generator signal has a 20ms period so 50Hz, but in the output the period is 90us???? So a ringing at that frequency isn't so bad right? (the initial peak goes up 1/5 the peak amplitude and then down in just 2us), but may be a couple of measurement with square wave at 50/1000/3000/10000Hz will be interesting, to see how the ringing behave at different frequencies. thanks for the video :)

How does it sound? Thats what matters

That's right, I am not able to 1:1 compare to many other amps, so I just had some general comments. I had a Xindak KT88 tube amp before, this is much more linear and open sounding, with more coherent soundstage. I would prefer this overall, and it is worth the price for what you get. It does not beat the soundstage and realism of my DIY amp, which as the Simplestark

Great stuff. Keep us updated with specs of these clones.
