It is not about me being happy. This is a site for facts and controlled tests, and the science says there is no way what you did would make a difference.

Now you,ve got to get that soldier out..
@diddley I dont see the point to soldier it out cuz now the amp works amazing
@Sved P there is no science behind your words, where are your measurements from my amp? this is a site for facts and controlled tests and I respect that
I just posted what I did and I know I am losing the warranty on my 3 years old amp
Only what I want to say is that those fastons I could easily move left/right and thats not good connection

Double Blind tests *did* show amplifiers to sound different
In many online debates, position taken by some that when amplifiers are used that have flat frequency response and low distortion that no double blind tests have shown them to sound different. Well, I managed to dig up a 32 year old test that says otherwise. What is fascinating is that one of...

A Molex connector like that is usually rated for about 3 amps. On 230volts that would equal about 700 watts of power before things start to melt. Ive hooked up a power consumption meter on the amp. It rarely consumes over 50watts of power.
The original design is sufficient. The odds of your modification being audible are zero.

Guys, you didnt read what I am pointing on... forget that molex connector and all this links
I am saying that its sad to see a good amplifier with a poor connection on the power supply side...I am not mentioning any poor connector that is not suitable for this amp
As I dont have any spare parts and I am not trying to invest more money into it, I decided to solder those connections and I came with very nice results
I posted this so maybe it will help some other guys here, if this is not the right way please delete all what I wrote here

That's just nonsense. Here is a 2kW amp with similar connections:

There doesn't seem to be any negative impact on performance.
So what are you saying? It's not a poor connector, however you removed it anyway to improve the connection?
Does it matter? It's a similar Molex connector, that's used in lots of amplifiers. Never has anyone proven that soldering them makes any difference whatsoever.

The most powerful amps I have seen (current too) had a 4-point JST connection for mains,with the inner 2 ones unconnected (probably for support) .
You DON'T solder mains if the company hasn't done it already at their own way and responsibility.

If the connection truly was (too) lose, it would have resulted in the amplifier shutting down randomly or sparks and smoke...
Ive checked the connectors on mine, they're perfectly fine. There's allot of issues with NAD products in their current line up. This is not one of them.

ok thanks for checking... to be more precise on mine they were good enough to not cause any issue but I could move them each with the finger
Please check this video, you will get it better
Starting at 0:10 the first black wire on the video was exactly like on my amp blue/brown wires

Those are 12V batteries, lower voltage thus high current. Hence why car jumper cables are so thick.
Never mind that the solution isn't soldering

Yep.Never mind that the solution isn't soldering
There are really nice locking crimps out there,with such a strong grip enough to take a blast with the only caveat the difficulty to unconnected them sometimes.
It could be defined as poor quality control...
Nowadays almost everyone uses faston connections (also found on washing machines etc.) the problem that the user says is that they were simply very loose, if they had been well fixed they would not have given any problem (not even psychological) some have the locking tab and are more stable, but seeing them so slow is not a good thing even if it has no influence on the performance.
Consider that class "D" amplifiers do not have the same high absorption as class "A-B" ones
I happened to see the same thing on 2-3000 euro speakers! the slow and weak contact, I simply tightened them with pliers.
Among other things, putting "faston" is a more expensive solution than the simple soldered wire... go figure.
