A wise sage once wrote: "The purpose of an amplifier is to amplify, ideally, without adding anything to the signal but gain.".....But what if an amplifier removes information? How would we know? I think Ncore amps remove information based on what I have heard on many different systems during our Tucson Summer Ncore Tour. Attendees agreed, but ....Frank Van Alstine has a more realistic view about measurements and more importantly what we can't measure......
I also find that class D amps remove information from the signal. In the form of tonal information and spatial information. Which is too bad, I like the idea of a small, efficient amp. But I won’t buy one until they solve these issues.
I don’t know enough about how the Class D technology works to know if there is more improvement to be discovered.
Perhaps if people took the time to learn how class d operates they would realize that no, the amp doesn't act as a filter on the signal.Interesting how different people's perceptions can be and how people assume it's the amp and not their own perceptions. It's like dinner time when I make a thai curry- "it's too spicy", "it's not salty enough", "it's not spicy enough", "it's too salty". Same curry, 4 different reactions. Now I can measure the salinity and hotness and come up with measurements that show it is neither spicy or salty on a relative scale, but some will still insist it's too spicy and too salty. Same curry. Same amp, same thing.
Me just a dumb uneducated audiophile. Good sound go in, bad sound come out.

Can the DAC be upgraded in these digital amplifiers?
lol...yeah, sure, just unplug your current dac and plug in a new one. By the way, they are class d, not digital amps. My son knows better than to jump into the deep end of the pool where the water is over his head. I would suggest you educate yourself a bit about class d amps before engaging in conversation as it is clear you are clueless about the subject matter.This isn't directed at you per se, but the more I read of people's snarky, misinformed comments about objective performance, the more it become clear that they simply have little to no comprehension of the technical side of audio. Specs are a foreign language that they don't understand and rather admit that damping factor, TIM, THD, load dependent frequency response, etc. are simply beyond their grasp, they compensate with sarcasm, snark, and insults. Sad.
I read somewhere that Ncore uses AKM chips and Purifi uses ESS chips. Seems they could be upgraded to change their sound quality.
So if I am correct AudioCircle is more of a "subjective" forum and there are other outlets to voice "objective" opinions?
My Hafler DH200 has distortion level of .001 so why does it sound different from a Digital Ncore amp?
You have a lot of reading to do...
Yeah, c'mon nc42acc! You didn't do your homework AGAIN?!? Tisk tisk. How can you show you face 'round here? Honestly...If the rest of us can read all the technical literature that goryu requires to keep us safe from ourselves and from exposure to harmful distortion, then you can too! You can't just skip the assignments and pretend to know what sounds good by ear. You must be trained and licensed by the authorities to make the important decisions about your audio system. It's only fair. Think of the children. Follow the science. C'MON MAN!
