Proof of evolution—Darwin Filters V2 for HiBy RS6, RS8, RS2, FC6

[7in1]

What a gem is a new Darwin Ultra filter!
I am enjoying my RS6 so much
The sound character is so lush and pleasing with my full sized headphones and with IEMs as well!
This player is a top notch for it's price category for sure!

No just plain lost where it is and how to use it. I swore i had a guide somewhere and i'd like to try it.

Hey @Joe Bloggs, I am wondering if you could expand on suitable use case for NOS non-filter?

You mention that with good equipment that can handle ultrasonic frequencies there shouldn't be an issue. I really enjoy NOS and non-filter is a something crazy I've never experienced - it feels so much more open and accurate than the regular NOS switch. I don't think I am very good at identifying SAF IMD in a pure listening test. What kind of category of headphone/IEM could handle that sort of thing?

I am currently running sennheiser ie600s and hifiman arya v1 and can't notice any IMD :/

Well... if it sounds good to you that's probably enough in this context

Having lots of spurious aliasing frequencies in the ultrasonic in your output shouldn't break anything in the way of headphones, it's just a matter of some headphones aliasing it back into the audible range, which *should* be undesirable, but audiophiles have liked worse theoretically undesirable things.

If you really want to identify whether your earphones are susceptible to this problem, try running a sine sweep up through the whole range of frequencies and see if you hear any spurious frequencies going *down* instead of up.
