Sweet spot of amplifier power

by Pedja Rogic, February 2014

According to the common wisdom, the relation between the amplifier power and its sound quality may look like the relation of equivalence. “The more the better.” The truth is, the best sound quality is associated with certain working points, which also implies certain power. Insisting on (often redundant) power, actually can and does compromise the sonic properties.

 

Designing the ultimate monolithic amplifier

The actual sonic report, and actual measurements.

 

Data and signal: are we progressing?

by Pedja Rogic, August 2013

Are bits still just bits? Let’s take a look from today’s point of view.

 

TDA1541A and Model S USB: 192 kHz?

Simultaneous data mode

TDA1541A today

TDA1541A grades and series

Another story about TDA1541A: 384 kHz

by Pedja Rogic, 2010 – 2017

A series of four articles discussing TDA1541(A) through its relation to Model S USB, written in 2010, and summing up the TDA1541A phenomenon. The fifth article was posted in September 2017, to shed another light on its sampling frequency bandwidth.

 

High resolution audio, asynchronous USB, oversampling, upsampling and stuff: The current state of affairs

by Pedja Rogic, November 2010

Do the PC and USB really fit into high quality audio today? This article is a reference point on these and similar topics. Written in 2010, it only got more important over time, showing Audial’s leading position. Must read for every ambitious audiophile.

 

S/PDIF or USB?

by Pedja Rogic, March 2008

The article discussing the major differences between the two principles. It is written in the days before asynchronous USB audio, but it remains the one that points out the main issues that should be addressed, not only in S/PDIF and USB, but also generally in the digital audio.
