the SINAD measurements

😂🤣🤣

@tomthiel the Kinki Studio power amplifier is indeed different animal, very powerful and transparent with a superior damping factor.

A technical description (taken from the excellent SoundNews review (*) can shed some light about it:

“The EX-M7 is a direct DC coupled power amplifier, meaning that it doesn’t have a single capacitor in the signal path, all the caps you see are used only for power filtering or for storing power for high dynamic swings. You should know that M7 is working in Class-AB, meaning that is consumes a lot of power, offers a lot of power in return and dissipates a lot of heat as well.

With a direct DC coupled design, offering a continuous power of 250W into 8 Ohms, 420W into 4 Ohms and almost double that number for some instantaneous dynamic swings, should result an ultra-fast response time, some world-class dynamics and an amazing transient response without affecting refinement or the detail and the transparency of the sound.

M7 is drawing power from two oversized and encapsulated 400VA toroidal transformers that can provide up to 72 Volts DC and 18 A peak current! I’m sorry, but all my past power amplifiers and integrated ones are sitting numb and silently in a corner. In terms of specs, the big guy simply outperformed them all.

The incredible spec sheet doesn’t stop here: 4 Exicon mosfets are driving the output stage – these are among the best you could possibly have, there are also 4 output transistors per channel (8 in total) that should provide an instant power delivery to your loudspeakers, some high-performance Mundorf caps for power filtering, 8 incredibly large blue caps per channel for storing DC power, another 2 smaller toroidal transformers, I see some juicy and oversized ceramic resistors, and the list goes on and on”

@devinplombier 

I imagine you understand this better than I do....LOL.....however "quiet" is emphasized...

@johnnotkathi,

Thank you for saving me from having to reply.

For those who might eschew the objective, and might prefer the subjective;

i suggest comparing the output with one’s ear in direct proximity of a loudspeakers drivers with source turned off: with most of the better new Class D amps compared to traditional  Class A or AB amps. I think most will typically find these  Class D amps to be quieter. I’m not suggesting the SINAD is the be all/ end all, but it is a measure of noise (and distortion) after all.

@audiofilio123,  Respectfully; if you subtract all the marketing fluff, those specs aren’t all that special.
