LDAC EQ on K9 Pro will also have

Hi Wilson , an other question

since the k9 have two USB and uses the fiio app aswell, will there be an option to attach a usb drive with music and play it from the app.

that would be a great feature.

I was checking the picture,
Where did you see the second usb? I only see 1usb B and that's all

I believe there an other on the side front right, if I’m not mistaken.

Yep there it is

@FiiO Willson While Topping and company fight their measurments war, what could really set you apart with this is having serious single-ended and balanced variable outputs, hopefully with analogue volume control (the fact that there is an analogue input suggests that may be the case).

DACs like the D90 sound great when using the fixed output, but when using them directly to power amps/active speakers out of the variable outputs, they sound dull, thin and lifeless (like most "digital preamps").

I want a non thx amp with opamps, opamps everywhere.

The USB Type-C port on the side, with OTG cable, can support cell phones and other OTG devices to play.

However, according to our previous experience, not all devices are supported, especially Android phones, because of the system settings, some phones can not play properly, which is a problem of the phone manufacturers, they do not operate according to the standard definition

Of course, most phones can.

This feature is an extra surprise, isn't it?

Yes, K9 Pro have analogue volume control

Yes, K9 Pro have analogue volume control

I'm sold, please send some to Chile

Hi willson

Do you have more details about the power Output?


I only found Balanced Output Power (Headphone): 2700mW/32 ohm, 1080mW/300 ohm
but to be honest that make not much sense to me
1080 in 300w is awesome, but 2.7w in 32 is to low, (unless is limited somehow?) usually as the ohms increase the power decreased example on another thx product:

• Output power: 6000 mW, 32 ohms, <1% THD (watts per channel)
• Output power: 800 mW, 300 ohms, <1% THD (watts per channel)
• Output power: 400 mW, 600 ohms, <1% THD (watts per
  
  32 ohms 6 watts vs 2.7, but then on 300 ohms only 800 vs 1080?
  

I am not an expert but it sound a bit weird to me.
apart from that do you know the power output for single-ended? and the output impedance of the device

last one..
product release still planing on July..are have been moved again..?

Please let us know
Thanks!

Hi, thank you very much for your attention!
Our current output power has not been fully determined, this is also the biggest problem facing by the technical engineering.
If the output power is too large, the 0dB signal continuous heat will be greater, the continuous working time is not long.
At the same time THD will become worse.

THX AMP is one of the biggest reasons for the current power limitation, but we have solved many problems so far, there are still some small problems to be confirmed.

The output power mentioned before may need to be corrected when the time comes, so I can't give you the exact parameters now.

Very sorry

Sorry, K9 Pro only support RX.
Which do you prefer, the TX or the RX, or both?
Most of the desktop decoders nowadays only have RX

Does tx require addtional hardware or is it a software thing to implement once you have the bluetooth chip?
I'd prefer have it in TX mode.
I use also bluetooth headphones on my PC. Some people might want to use some BT speakers.

I'd prefer to have a RX+TX unit on my desktop.

There are few Bluetooth chips that support TX mode, because we need to do TX with LDAC and aptX, so there are few chips that can do it now.
Currently only CSR8675 can do TX full format support, QCC series currently does not have the supporting code.
If QCC series chips can support TX perfectly, I think we will follow up soon.

We have a product called BTA30, which is a Bluetooth product that supports both TX and RX as well as DAC, and it is very powerful, you may consider it.

I would rather have a little less power but lower noise floor and lower THD/IMD numbers across the audible frequency spectrum.

I don't know why some people think every headphone needs several watts to sound good. That makes no sense!

It is possible that they have high resistance headphones, or headphones that require high power to drive~~
