Sabaj A30a announced

How comes? Can you elaborate a bit more?

Update: I've gone back to my 2019 Sabaj A20a amp, and I now prefer it to the A30a.

I can't talk about it because I haven't done an ABX test.

I had the chance to listen to the Sabaj A30a and ended up taking some photos of the inside and i could not find the AXIGN chip anywhere...the amp sounded fine but it kept shutting down on loud transients...may be you guys can comment about these photos?

Here (AXIGN chip)..:

The SMSL sdb setting is identical to using the tone controls with treble at +4 dB and bass at +5 dB - at least in my ao200 (measurements in this thread). And those tone controls come 'for free' in the analog volume-control chip they use in many of their products. There is nothing magic about...

As you can see, we also can't see the STA516BE chipset, which probably means the AX5689 chipset must be underneath the PCB. We can also deduce that the cooling system is underneath.

Obviously, you did not click on my answer... (cause you would have seen the STA and AX...)

The circuits and ICs have already been discussed; this starts around post #1050-#1080 in this thread.

The switching off only occurs with very few loudspeakers where the crossover becomes extremely low-impedance far above the audible frequency.
Often, the problem can be solved by modifying the crossover. This is discussed starting with post #1799, and possibly earlier.

Thank you, @Vlasis, what speakers/subs are you useing with the A30a and do you have an impedance graph of these speakers?....
