Give me a phono pre-amp and I'll bite.

I think a variable volume output from the DAC (which both AKM and ESS DACs current lineup support) for the pre-out would solidify the deal for me.

If these had a bass boost option like the K3, this would definitely be a must buy for me please make it happen Fiio

An additional output switch (similar to the input switch) for the output ports (XLR/4.4mm/6.35mm) would be nice to have, so you don't have to unplug, when connected to different headphones in parallel.

Swappable opamps?

 

[Kean FiiO]

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.

Even for single-ended inputs, our goal is to use the same circuit as balanced amplification.

Swappable opamps?

You know, THX AAA specifies the OP AMP model can't change

 

[meowcs]

All i want is USB type B port.

Ture.

May we have a cheaper model with less connectors and in a smaller form factor?

@Kean FiiO

Do you already have a target MSRP?

Another vote for AKM chips in this please <3
I can't wait to get one of these for my desk at work.

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.



Note：This picture is only a layout of K7 interface, not the ID concept.



Here are some features and configuration introductions：
1,K7 is not necessarily a flagship model
2,Built-in dual THX AAA AMP architecture and balanced headphone interface. Higher power output than K5 Pro
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.

It would be great to have two versions, one with and one without a dac.

If that is not possible, it would be great to allow use of the internal dac with an external amp, or vice versa.

The rendering above does in fact show both RCA and XLR outputs, so I think you're covered there.

I'd agree with the preference someone expressed above for USB-B input; seems pretty standard for a desktop product, as opposed to USB-C.

I'd also agree with the thought above that it would be nice to have a 3.5mm jack. I'm a big fan of avoiding the need for any adapters. Maybe it could go where the 4.4 is shown above, and the 4.4 could be moved over next to the XLR, keep the balanced stuff together? (And I suppose if we're in "daydreaming about no adapters" territory, maybe you could even squeeze in a 2.5 balanced over there as well!)

@Kean FiiO will you consider getting power to a similar level as the 789? as I find the monoprice combo is a little low with 3120mw.

Honestly if price and power is good you can have my money.

 

[Imusicman]

Dual AKM gets my vote. I would also like to a specific connection for Fiio DAPS such as the M11 Pro or M15 similar to one used on the Sony TA-ZHiES
