Topping dx3 pro and filters

[davidebond]

Hi. The Topping dx3 pro has 6 filters which were discussed by you elsewhere: https://www.audiosciencereview.com/...l-simple-understanding-topping-dx3-pro.32262/

and: https://addictedtoaudio.com.au/blogs/how-to/how-to-pick-the-best-filter-setting-for-your-dac

Unfortunately, notwithstanding having in my bookshelf the handbook by Nielsen and Chang, I didn't understand. What are the meaning of the filters, explained trivially? They are:

1. sharp roll off filter
2. slow roll off filter
3. short delay sharp roll off filter
4. short delay slow low roll off filter
5. super slow low roll off filter
6. low dispertion short delay filter

Addicted to audio suggested to use a fast roll off or a short roll off with a linear phase, but how can I set a linear phase in the dx3?

Is there one who can explain these filters in a simple manner?

Thanks and best,

davide

3. short delay sharp roll off filter

Just pick the default F-3 or F-1 IMO... set and forget. It's very difficult to pick any difference between them all anyway.

This is a review and detailed measurements of the Topping DX3 Pro+ DAC and headphone amplifier. It is a replacement for one of my most favorite combo products, the DX3 Pro. It was sent to me by the company and costs US $199. The DX3 Pro+ maintains the gorgeous and high contrast orange LEDs...

Yes, their main function is to make the "features" list in the marketing material slightly longer, not kidding.
And due to such marketing eventually some people may feel they "need" them, and may choose another product if they are not there.

I use F1 or whatever they have chosen to call the sharp standard filter. That is the technically most correct one and the only one needed really.

But don't take my word for it, If you are curious, try them out, it is only the NOS/Filter less settings that can hurt anything.

To @JSmith : it is was I done. Thank you. To @Calleberg : I try it. At the moment, I am using the F-3.

Hello, so according the article, for dx3 pro, what is the one to pick, F3 or F 7,
Fast roll off or Fast roll off linear?

Can you hear a difference between any of them?

No, I really can't, just interesting which one in the article is referring to.
