Yes @ 1Khz. What's better about 36K than 47k? I personally prefer the 1.8K of the NC-500's

1.8K is OK if you have a preamp or DAC with low output impedance (such as proper studio gear), but with 1.8K, you might run into issues with consumer stuff.
No - a sticky button is a mechanical issue. Either a bad or a very dirty/dusty switch.

As usual you lost common sense and interprete specifications to your "advantage".
1k8 is the input impedance of the ncore power stage (per leg to be precise), so the "input" after the necessary input stage/buffer (that's why it is called a buffer stage.....able to drive that 1k8 input impedance of the power stage).
The real input has input impedance comparable to all other power amps (but I at least hope that you knew that already
).Bashing the competition based on false arguments is not what we are waiting for...

We are talking about the input impedance of the amp modules themselves. I'm not sure where there's any bashing going on here. The reason I prefer the 1.8k is because there's no cheap IC opamp buffers in the path killing the sound with the NC-500's.
Then it might have been clearer if you had stated "I can live with the limitations imposed by the low 1.8K input impedance in exchange for not having cheap IC opamps that in my opinion reduce the sound quality".
Funny enough, the NC400 has a 100K input impedance despite not having any cheap IC opamps...
Virtually all commercial icepower based hifi amps have had to have some form of buffer stage in order to play nice with the source up stream due to low input impedance.
With the 700ASC2 this would not be the case.
I'm looking for a module to drive the woofer system of a 3 way active design, in that regards the 700ASC looks very plug'n'play.

Yes it has built on discrete buffers. But like all Hypex OEM amps (besides the mp series), you can bypass the buffer or there's no buffer. Not an option on the Icepower. The Hypex MP series uses NE5532 based buffers.
I'll sell you one if you want. Has about 15 minutes of time on it. It's not a bad amp. Best high powered Icepower yet. But I'm just spoiled by the NC-500's
For subwoofers it will be great. The problem with the amp is at the top end. The modulator and lowpass filter is clearly inferior to the Ncore amps.
The real limitation is not being able to bypass the buffer. You can always add a buffer of any grade if there's no buffer or option to bypass the on-board buffer. It would be nice to see all of the all in 1 integrated amps (PS and amp on 1 board) with a header pin buffer bypass jumper.

So how about talking about that, instead of the rather oblique praise for low input impedance?
Yes. Why would you want the extra circuitry of 2 buffers in the path if the preamp has more than enough grunt on it's own? The very best buffer is no buffer. Nothing measures better than 1cm of copper PCB traces
