No new version about A22, but X26 Pro will come up quickly.

Any news on the release date of the H16?

Here is the last version (4.86) for X26, A22, A18 and U16:

Coming soon...

Optical? I don't use, but you never know.

MQA? HUGE no thanks!

Are they going to add the MQA $100 fee to the price of the unit, like the SU-9, D90 MQA and M400 dacs, . I will be happy when MQA is retired.

Probably.

MQA is a total and complete nonsense (even more on a hi-end audio quality product).

Too bad somes are buying that crap.

I’m curious as to no optical spdif input? Also, what level on volume control to achieve 5V?

Looks like Gustard Dac's don't want being purchased by Optical audio-only user like me

Sounds like a job for the SPDIF ipurifier from ifi. It will convert the toslink to coax, or vice versa. Reclocking/regenerating along the way.

Will Ifi Purifier or similiar products make a better job for me that mostly use Playstation 3 for listening music with CD's and gaming, and Ps4 Pro for gaming and entertainment? Playstation 5 unfortunately will not have Optical output, but maybe newer versions will have.
Ifi Purifier simply works output the Optical audio by Ps4 for example, into Ifi will reclock etc. and will output a Coaxial transmission into the Dac? Will it be better than just Ps4 into Dac via Optical? Looks like Ps5 and Gustard A18 can't never be friends D:

A new version with optical out (good to have for televisions and consoles).
Very nice, waited for this, though I don't like and don't want to use MQA too and thus pay a hefty price incraase for that : /

@Gradius
Do you know how to contact the employee of gustard outside of that e-mail address [email protected]?

@WolfX-700
Can you please tell what the xlr and rca input and output impedance is?
I don't fully understand the last picture of the measurement ^^
The topping A90 has a xlr input impedance of 2k Ohm. Amirm says a 10:1 ratio is fine.
A good pairing?

And: What settings to set the channel to 4 and 5 V?
Thanks!

Updated their page in ... 2017 !

-2db 5V -4 4V

Is it the same for the 3V RCA output? -4dB get 2V??

And in pure DAC mode... The XLR fixed 4V or 6V?

 

[Ddd]

Does the A18 have a volume bypass "dac only" mode?

Yes it has it. Not in the menu. But have to do it from the remote. Is mentioned in the manual

The output impedance of the XLR output is mentioned in the manual if I'm not wrong.

-2dB 5V
-4dB 4V

Would they use the latest and greatest Optical receiver for better sound out of it? Would like to know also the price, since i would use only Optical!

 

[Oklei]

RCA Output level：3Vrms (VOLUME 00dB)
Output impedance 100 ohms
XLR Output level：6.0Vrms (VOLUME 00dB)
Output impedance 100 ohms

Output impedance the same for balanced and se? Suspicious.

How come Wolf has not posted any new updates? Hope he is okay. I miss the reviews on all the cool new unreleased products.
