It would be extremely useful to have the possibility to set a cut off frequency lower than 70 Hz for the SW output Using the latest DSP chip with ST high-power amplifier chip, carefully designed and debugged, its distortion is as low as 0.0008%; Minimalist design although not everyone will like the gold Sabaj logo and the handles on the front plate If A30a is connected to the high level input of SW, a short circuit condition may occur inside SW and destroy A30a.

And this is still the case for the actual loudspeaker transducers inside "powered speakers" that have amplifiers built into them... It's also true that, while there are a lot of current digital signal standards and formats, analog audio signals are still far more "standardized".) Subwoofer output level..............................................................................2Vrms Due to the new Axign-Full Digital Amplification technology it can probably compete with AB class amplifiers that cost 3 to 5 times more It's also worth understanding that most modern "Class-D amplifiers" are really just "a DAC that puts out enough power to run speakers".
THD+N ................................................................................................0.0008% In the case of SE output, the negative side of R-ch and L-ch is connected to the ground, and the + terminal is 0V with no voltage applied, so there is no need to worry about short circuits.

It is technically possible to design a Class-D amplifier that directly accepts an analog input (including a basic PWM design)... Of these, only the SE (single-ended) type and PSE (parallel single-ended) type are capable of high-level input through speaker output. I also want to try my DC-1 just as a preamp. I’ve read it’s a nice analog resistor ladder? I’m wondering how the volume is handled in the Topping.

I'm coming out of the Creative X7, and from my subjective taste, there is a clear improvement in sound quality, so in that regard, I'm quite satisfied.

here I must rely on the built-in drivers, however from some weird reason, macOS master volume control is grayed out, and I have to use a 3rd party software called SoundSource to be able to control the volume. That is very annoying, and I hope Sabaj can fix their firmware to allow volume control under MacOS. Built-in multiple EQ modes and high/bass adjustment functions to easily match various speakers and music;This is available on Prime sporadically and I would suggest going there for a trial that can safely be returned. Incidentally there is talk of feature problems and they have been mostly fixed with V1.12. This had to do with subwoofer volume and defeat. Channel separation ...................................................................................108dB It would be also useful to have the possibility to have as an option a full frequency range output for the SW sub volume is not consistent with speaker volume. They rise and fall unevenly. At low volumes you may have way too much sub, and at high volumes it disappears. This means you have to adjust the sub volume every time you adjust the main volume.
Great Deal
