Hi. Can you check if coax can play 192khz? Thanks.

Oh. Either I'm doing it wrong or my T2P is defective.

What the Tone2 Pro does with the signal internally I have no way of knowing, but it is being fed a 24 bit 192kHz FLAC. I have the device set to Coax (not Auto) and have a power bank providing the 5v.
I think I have narrowed down the problem to the coaxial output of my NAD C565BEE. But I have not figured out exactly the cause. If I use coaxial direct from DAP to T2P it is ok it can play 192khz. But if I pass it through the optical input of the NAD then output coaxial to T2P, it cannot play 192khz.

some optical ports are restricted to 24 bit 96kHz

I understand this.

But I can see the NAD show 192khz in this set up: DAP>> Optical >> NAD >> Speaker Amp >> Speakers, and it plays 192khz.
Also with the Mojo: DAP >> Optical >> NAD >> Coaxial out >> Mojo >> Speaker Amp >> Speakers, it plays 192khz.
But, with T2P: DAP>>Optical>>NAD>>Coaxial Out >> T2P>> Speaker Amp>> Speakers, no sound, unless I set the NAD to downsample to 96khz.

I don't use roon. I stream directly from Tidal or play local files from my WM1A.

Is the update fixable by firmware?
Yep But not on yours i think. The first production runs has an issue where firmware uødating doesnt work as intented. Need to us an ST-Link to update it

Bummer.

Edit: Nah. Everything's gonna be alright.

Sounds really promising! The measurements for it is incredible good though! And the updated version(the one i preordered) have some small stuff fixed. Im gonna use it as an amp also since im mostly use IEMs. So now i need to find i cheap good cable with 4.4 termination:)

BTW, do you use Roon?
How can I know if my T2P is the updated version?

So has anyone been able to compare the Tone2 Pro to the current crop of DAPs?

At the moment all of my DAC/amp devices use my phone or PC as a source. Sometimes I’d like to be able to just plug in and press play, so I’m looking at Android DAPs. But I don’t know where to aim to get similar SQ. For instance the new Hiby R6 2020, from a specs sheet perspective, looks like the Tone2 Pro, with a screen and Android... for a $500 premium.

I’d rather get something less expensive since these players and their fixed Android implementation all have a pretty close expiry date. But to drive the IMR Semper or my Final Sonorous VI I need something good. Where would you guys place the Tone2 Pro compared to DAP?

Just adding my 2 cents. I like almost everything about Tone 2 pro, especially the sound that's great. If you can utilize a balanced connection, please do, it will be worth it. My only wish is if it was just a bit weightier so it can hold position even when heavier/rigid RCA cables are attached... but then it wouldn't be as portable and cute. :relaxed:
