Sure, but then you need to look into the imd graph.Misleading as music and sounds don't just occur at 1khz or 6khz.

The full story is that during a QC run of testing at Hypex back in late Spring 2022 an issue (I do not have the specifics) was detected regarding the NC502MP's only.I received my 6-channel NC502 build. Everything looks excellent, and dealing with Dylan was also excellent. He always kept me informed and was very open and honest about anything regarding delays or issues.
One question, during my order and build time there was a shortage of the 502 modules. I'm not sure if it was just a shortage or if there were problems that caused them to pause production. But I did get a snippet talking about testing of the "new" modules and at one point I think some of the tests either failed or weren't up to quality standards.
None of that was an issue for me, but I was curious if there was anything changed during that time? I wonder if the new modules would test the same as the ones in this review or if there might be minor changes or improvements. If anything, I'm sure they are slightly better as these things tend to get better not worse.

When speakers reviewed here are praised for their ruler-flat response I'm surprised this amp was given a positive conclusion considering it's down half a dB at 20k and even shows some depression at 10k, when amps like the Schiit Tyr, an apparently solid A/B design is literally RULER FLAT right out to 20k (and down to 20 Hz, and with excellently low distortion and lots of power, although less than the class D amps).Conclusions
While still way ahead of countless amplifier designs, the Hypex NC502MP modules are built more for power than ultra low distortion. Not a bad compromise considering the fact that running out of power is quite audible and rise in distortion probably not. Beauty of class D amplification is showcased by Buckeye in producing six times 600 watts of amplification in a light, and compact case. I will do a teardown later but so far, I am happy with what is there, sans the upside down XLR connectors.

Are you referring to class D when you state, "Digital amp?"It would have been fun to say a highly recommended digital amp has worse measured performance than a reasonably good tube amp.
yes, in that case I was referring to the 502MP amp in the review. I know that earlier I compared it to a solid state A/B amp (the Tyr) and then later referred to tube amps. The Tyr was just to illustrate a flaw in the 502MP. Comparing the 502MP to a tube amp was for the entertainment value.Are you referring to class D when you state, "Digital amp?"
I see. Class D amps are not digital. I know they use square waves that make things seem digital although the analogue signal is riding on the flats of those square waves and the entire process is analogue. So they are not digital amps.yes, in that case I was referring to the 502MP amp in the review.

oh noes, you caught me. yes, not digital...I see. Class D amps are not digital. I know they use square waves that make things seem digital although the analogue signal is riding on the flats of those square waves and the entire process is analogue. So they are not digital amps.
and at that point you may as well just pull a 30 amp 3 conductor. No point in screwing around. Keep the old one and add 7,200 watts more.That's kinda tough without knowing what wall issues there are as a new home run will need to be pulled.
This may have been true but is no longer.Amir has stated on so many occasions he never factors in price.
