AYA 5
Continuing the AYA story, we are about to release the AYA 5. And we are making some significant changes with this version.

USB interface and AYA 2021 editions [poll]
According to the feedback we got recently, the interest in the USB interface and AYA projects may have re-emerged. And in case we find it adequate, we will go and release one or both of these projects again, as limited series.

Amplifier A20
In April, Audial will come with a second release for 2021, a stereo amplifier A20. As opposed to its predecessor, Model A, the A20 brings five inputs, conventional 45 kOhm input impedance, revised exterior with LCD, and revised Audial-made copper binding posts as a standard feature.
General
Audial and coronavirus pandemic
We want to thank everyone who wrote previous days, asking about how the pandemic develops in Serbia, and how it affects the things with Audial. Even though the things work slower than usual, there is no real outage for now. Anyhow, we will process and ship every order. And also lower the prices during this time.

Model S will be discontinued by the end of this year
The Model S DAC has been initially released 11 years ago. A current version of this reference TDA1541A D/A converter, a Mark3, will be the last one, and it will be gradually discontinued by the end of this year.

AYA 4, second run
The AYA 4 was a very nice project, and it apparently remained on your radar way after the originally produced quantity was sold out. So we will make it one more time.
Technical
Classic and transformer coupling: System grounding difference
The use of signal coupling transformers requires a somewhat different approach to the system grounding.

AYA 4: This year’s AYA release, featuring 192/384 kHz async USB
AYA 4 is 2018 AYA release, with all the features of previous AYA II DACs, and completely changed, now no-compromise, 192 or 384 kHz capable asynchronous USB stage. AYA 4 can be used as usual stereo DAC, but its USB input stage can be also made as 4 channel interface.

Model S4 is coming
Model S4 comes to show how real audiophile reference USB DAC sounds today. It also includes acclaimed and well known Audial S/PDIF quality input.

Back to the roots: 14 bits (of TDA1541A)
By measuring standard low level performance at -60 dBFS (dithered sine wave), there was practically no difference between its regular 16 bit, and this 14 bit “mode” of operation. Noise floor, on the other hand, is somewhat higher, roughly speaking 6-12 dB, and that is what you would expect, given 2 bits difference.
