and I just took a look at the M-dac measurements, the filters do things for a couple of Db in frequency’s barely audible to the human ears (especially when you are above ~30). So again, also on the m-dac: I challenge you to a blind test

 

[ATimoff]

Right! If we like the sound, then we have a good device. Further, you can not study it. Accept as is. I will expand the meaning. When marketers hang noodles on our ears. It is useful to look at independent measurements. In order not to be disappointed in a future purchase.

Digital filters are about impulse response. There is no need to look at the level of harmonics. Out of earshot.

Which Topping DAC/AMP you were comparing this with? I have A30 Pro and looking to buy a DAC for it. I am thinking of buying K9 Pro as single solution.
How good is the AMP on K9 Pro compared to the Topping/SMSL?

I've tested D30 Pro (with A30 Pro too), Topping combo is slightly more neutral and focused on microcontrast to my ears. Probably we need to wait for ESS version to compare. But subjectively, owning A30 Pro, I'd just bought D30 Pro for it, it's simpler than selling A30 and then buying K9. But maybe K9 Pro ESS will be a beater and I'll change this opinion

Thanks, I will wait until K9 Pro is back in stock and wait for ESS review.

@cleg Tell me please. Did the digital filters somehow manifest themselves while listening? For example, on the attack of sound. Or is it a useless functional - the fruit of self-hypnosis? I am looking for a replacement for M-DAC.

Remote volume control via bluetooth seems to be working with the most recent stable firmware release already, just tested it with my application.
Also there seems to be an option for toggling MQA support, haven't seen that feature in the official control app yet.

So for those wondering, there will most likely be support for remote volume adjustment in the future.

What recent stable firmware release are you referring to? Isn't V1.13 the latest?

Yes. Tested with 1.13 and BT firmware 1.0.

 

[Bob Ley]

Yes. Tested with 1.13 and BT firmware 1.0.

Where do you see the Remote volume control and option for toggling MQA support.
Also, I like the eq presets but the custom one sounds very bad for some reason regardless of how I set it.

It is not yet supported by the official Fiio Control app, im just messing with what i've datamined in my custom control app.

ok, any idea about the custom eq option, why it doesn't sound good compared to the presets?

Another review:

 

[WorksUnit]

I am a little used to Low pass filters having dabbled with music production for a a couple of years.
The inbuilt ones on the K9Pro do nothing, tested with different Headphones over a week or two, BT and USB.
I do want to believe though, fantastic sound for me.... perhaps it is a software thing, and the K9pro will evolve.

Thanks! Timely clarification. I was already beginning to doubt my hearing. After all, I'm over 30. Almost an old man. Perhaps for the ESS version, the expert will clarify information on filters. It is interesting.
