The reconstruction filter *is* part of the "sound characteristic" of the DAC. Turning it off (assuming the DAC in question actually lets you do so) prevents it from doing its job correctly.
Okay. Are you saying that you have to use a filter? Thanks for the feedback.
I prefer a filter that is close to linear, but I also know that this is not necessarily the right answer. And I know that filter preferences can change depending on sound taste. I first try using a filter that is as linear as possible, and then try other filters.
If I can turn off the filter, I turn it off. Then I choose a filter and listen. I test various cases.
Do you actually know what this filter is for and what it does?
I know the basic role and content of filters. Digital filters are a type of low-pass filter, and they gradually attenuate signals in the high-frequency range. They are used to reduce distortion (aliasing) according to the sampling rate in the digital signal processing process and adjust the sound quality.
I know. I know, but if I can turn off the filter, I turn it off, or if not, I use the most linear filter possible and listen first. Then I apply the filters. That's just how I usually test new products.
Filters are a matter of personal preference.
There have been 'hit and run' situations where members edited their posts and claimed they never said this or that (usually insults).
Oh, so that's why it can't be deleted. Got it. I'll be careful when I use it!
I know you guys like the measurement, but I just said the result according to my taste. Don't think it means anything. I listen to it because I have a lot of DSD sources and I like listening to DSD format more than FLAC. Whether DSD is theoretically meaningless or not, I listen to it because I like DSD better with my ears.
Actually I moved your post here.
It's been moved. I thought I wrote it wrong. I didn't see the video. I'll watch it later.
Can I suggest that now is a good time to read more and learn more about the importance of listening controls, and why sighted listening without controls (level matching, blind etc) are so unreliable
Right. I think that your emphasis on objective results through "measurement" is a good tool for reaching a reasonable conclusion. As I mentioned in other articles, I unconditionally look at the measurement values of products that others have measured and tested.
I graduated from an engineering college, not a liberal arts major. I like measuring. I also like scientific theories. I also enjoy explaining things theoretically.
That's why I'm posting and reading your articles.
The "analog" content that I've experienced so far is the most important point that you guys talk about, such as human illusions and placebo effects, which are the brains that make illusions or can't distinguish.
However, just because I didn't physically measure it, my experience isn't necessarily meaningless. I've had various experiences, not just listening to music.
I've had more diverse experiences than you think, but these experiences aren't meaningless.
I'm talking to you guys right now to approach my experiences theoretically.
And I'm learning along the way.
I'm not just spending my time building my audio system right now, but I'm also writing diligently to learn more things that will help me objectively in my future audio experiences.
Anyway, I admit that you guys are right. That's why I'm going to buy an SMSL DAC and a Class D amplifier.
