TDA1541A reference. Non-oversampling, 384 kHz capable. Zero-feedback output stage.
The most powerful and the biggest Audial amplifier so far. And there is more to it than meets the eye.
The sweetest twenty Watts. With tone, ambience and spaciousness, and pinpoint soundstage.
Recently we got two nice video reviews
The one by James Owens of ABX-Audiophiles, who tested and kept the A21 amplifier in his system as a solid-state reference for other tests.
And the other by Mark Cargill and Elite Audio UK, who unboxed the S5 DAC and liked it very much.
Hope you will enjoy watching, as we did.
Remote control unit
Audial remote control is designed to work with all current and upcoming Audial devices supporting remote control operation.
And it is a unique remote control, in a CNC machined maple case, finished with high-quality single-coat oil, for a superb tactile feel and mechanical protection.
Later this year, we will release a similar unit in a machined aluminum case.

USB interface board Mk3
In the autumn of 2023, we released a limited series of the third version of the Audial USB board. It is an asynchronous USB interface, with low jitter clocks and galvanic isolation. It supports up to 4-channel 384 kHz operation with Philips simultaneous data output, or up to 8-channel 192 kHz operation with I2S output.

This blog post brings more details on this fine amp.
Connecting the S5 transformer coupled RCA output to the A21 balanced input
S5 transformer coupled RCA output can also act as a real balanced source, and thus it can be connected to A21 balanced input.
“Is I2S better than USB?”
Hopefully, this article will summarize the situation and clarify some doubts.
Continuing the AYA story, we released the AYA 5, and made some significant changes with this version.
Story of Asta
Read about the Asta DAC development process, and have a first look inside.
PC: Today’s grey area of hi-fi experience
So, it is a tricky zone to be in. But we tried to shed some light on the subject, from an esthetically oriented, rationalist point of view.
Transformer output coupling
Audial reference DACs offer the transformer output coupling possibility. These two articles describe the major differences between the transformer and usual capacitor coupling and the different approaches to system grounding.
Another story about TDA1541A: 384 kHz
So, is it 384 kHz capable?
Back to the roots: 14 bits (of TDA1541A)
How much does the number of bits matter? TDA1541A distortion performance shows no practical difference between its regular 16-bit, and 14-bit “mode” of operation. When it comes to the ladder (“R-2R”) DACs distortion, it looks like everything is about converter accuracy. More bits improve only on the S/N ratio.
