the TB is a relatively very good DAC; an rpi is somewhat noisier piece of electronic for a very serious hifi setup, and the TB does not accept (afaik) I2S inputs but only unbalanced coaxial spdif (and USB which has its issues)
For all my compunents I have build separate lineair power supply’s. I use a HifiBerry Digi+ Pro with an Allo Isolator to keep noise as low as posible (since you cannot filter all the noise out). I am currently thinking of buying an DDDAC 1794 (really worth looking it up), to connect to the Digi+ Pro via I2S
back to some suggestions on how better could the next TB :
I suggest it will accept balanced AES-EBU inputs and toslink; and it should do some DSP crossovering and eq to be able to output balanced analog audio signals to separate SUB, BASS, MIDS and HIGH pure analog amplifiers
Any further update on the new tone board?

Any new about the future upgraded tone board? Will it be released this month or there is any estimated release date?
Can’t wait to hear at least some info about the status of the project!

From what I’ve read, Ben, the designer of the TB left to start another company. Likely why there’s no updated version.
Hello All!..
We can read recently on Khadas Blog, that a v2.00 frimware version is downloadable…
Because of the title says “Tone 1: Upgrade to the Official Khadas Firmware (v2.00)”,
I wonder if this v2.00 firmware version is compatible to my Tone-board ?
In fact, are Tone1 and Tone-board the same boards or there is any differences between these behind these two names ?
Hello, I believe it works for both Tone1 and Tone2. Install it once and your good to go for both boards, individually or simultaneously…
From the Blog post…
"Why does the Tone1 need the v2.00 firmware upgrade?:
Tone1’s latest software update includes a new USB Driver and DFU Tool (v4.86), and we’ve listed the most important changes below:
Seamless compatibility with the Khadas Audio Dashboard (Windows Tray Tool)
Tone Series DFU Tool can upgrade both Tone1 and Tone2 devices
Use both Tone1 and Tone2 simultaneously, without reinstalling drivers
Unique Khadas VID (Vendor-ID, Khadas is now a registered USB-IF Member)
Unique Khadas Manufacturer Name"
I followed the steps, all went well and as expected.

Yep, same board just a new name.
Hello All!..
Thanks RDFTKV and Gouwa for your answers 
…
Ok, Gouwa, now I’m sure Tone-board and Tone1 are the same boards,
now I can go further in my Tone-board upgrade…
Ok, RDFTKV, will try to upgrade my Tone-board as explained on the blog post…
By the way, I also got a VIM3 Android 9.0 Pie embeded (actual Tone-board is mounted on Nougat v7.1 VIM2), any news about TONE2 version or the project is stopped as labjr said ?
What is the schedule for Tone 2 Pro VIM version be available?

Hey! you can already order it from the official website
I think the user wants to know when the Khadas Tone 2 will be available. Khadas has previously said Q1 2021.

The shipment of the second batch, as indicated by the link, is the beginning of February, as I understand it, we are talking about Tone 2 Pro.
I meant to ask the schedule for the Tone 2 board for VIM not the standalone Tone 2 Pro.

Latest news I have heard about it.
Bare board version is currently named the Tone 2.
Hello All,…
As we are talking about Next Generation Tone Boards…
We all know that Tone1 (previously named Tone-Board) in it’s VIM version (40 pins header) can be used on both VIM2 and VIM3 boards…
Tone2 VIM version will be (Q1 2021) Tone1 VIM version evolution but not the same as the Tone2 Pro…
I wonder if anybody here has tried to weld 40 pins header on a Tone2 Pro to use it plugged on WIM2 or VIM3 as Tone1 VIM version ?
@DerFu tone2pro doesn’t have connectors I guess, its sealed at the bottom
the tone 2 vim board was still in decision making for the mounting procedure as I have last recalled, it will either be top mounted to GPIO and get input via the I2S, or have a small bottom PCB to connect the Tone’s USB to the USB on the PCIe connector bus…
check the original tone 2 thread for pictures and other info about it 
cheers
