Amplifier A21

As announced about a year ago, the Model A, which was available in 25 W and 50 W versions, was scheduled to be replaced by two new amplifiers.

The first was the A20 (20 W), and now we are going to release the A21 (100 W).

Amplifier A20

As opposed to its predecessor, Model A, the A20 brings five inputs, conventional 45 kOhm input impedance, revised exterior with OLED display, and revised Audial-made copper binding posts as a standard feature.

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 S/N ratio.

Transformer output coupling

Audial reference DACs offer the transformer output coupling possibility. These two articles describe the major differences between the transformer and more conventional capacitor coupling, as well as the different approaches to system grounding.

Firmware updates for USB interface boards

Firmware version 3.5 enables 352.8 kHz and 384 kHz support with TDA1541A simultaneous data or PCM1704 output.

Version 3.6 brings 4-channel functionality with I2S output. That way the USB board with firmware 3.6 and two stereo DACs can be also used as a two-way digital crossover.

These updates are available for download for both original, and Mk2 USB interface board version.
