After the K3 and K5Pro went on the market, we received a lot of planning consultations about more advanced desktop DAC&AMP K7. Some people care about the performance of the amp, and others care about the extended capabilities of the product. Indeed, in these two aspects, there are still many improvements when upgrade K5Pro to K7.
In order to make products that better meet your needs , we open the plan and look forward to your feedback.

3,Xmos core, support 768k&DSD512 USB DAC and SPDIF input
4,LDAC Bluetooth receiver&BLE app control for more audio settings
5,AKM or ESS high performance audio DAC chip(TBD)


For other specifications or features you want, please suggest to us. You can also share your common use situation and your equipment.

One feature I would love to see would be to have the optical and coaxial inputs be individually selectable, which is a really common feature that's found on just about all DACs.

And also maybe include a 3.5mm jack so that you don't need to use a 3.5mm-to-6.35mm adapter.

Wow, was looking to buy the Monoprice THX 887 this Summer but if this is happening this year then I'll wait.

A really good AKM DAC Chip would be great.

I'm a bit sad about too much ESS Hype. :)

I just want to discuss the necessity of this switch, not that's difficult to achieve it.
K5Pro has a same design: Optical is automatically disconnected when coaxial is inserted. I thought the customer just need two different interfaces(socket), not two signals at the same time.

Wow! Count me in. I’m all for this, ticks all the boxes I need for an all-in-one desktop solution. Here’s just hoping Fiio will keep the pricing considerably low and on-par with the budget conscious. The reason why the Schiits, the SMSLs, the JDS Atom and the Toppings is that they’re bang-for-buck performance yet still very affordable and what sets them apart in the market is that they don’t change models often (usually 3-4 year product lifespan).

In my set-up, I use a USB-to-SPDIF converter so I can use two separate DACs. DAC-1 is used only for my desktop speakers, DAC-2 is used for my headphone amp. I also have a CD player connected to DAC-2, so this means that the DAC needs to have at least two individually selectable SPDIF inputs for it to work in my system.

Plus, I can think of many other possible system senarios were having two individually selectable SPDIF inputs would be a desired (or even a nessassary feature) for a DAC to have.

Go further step ahead. Maybe a M15 desktop version.

Say add a balanced THX AAA amp and bigger storage: SD, 2.5 HDD or USB.

Really nice feature set! I wish you well with it.

If someone uses the unbalanced analog input, what is the mechanism to make it balanced? (Or is only 1/2 the balanced amp circuit utilized or a simple phase inverter opamp reversing the input?) That is one thing I really like about the Mjolnir. It uses a circlotron-style topology to balance an unbalanced input.
