How Do the Current Soundbars Perform? Putting Bowers & Wilkins Panorama 2 and Focal Dimension to The Test

To narrow down the field of compact equipment with a healthy degree of skepticism, there's no need for a degree in physics. While so much can be said for speaker design and the sound intervention from the with more sophisticated digital signal processors (DSP) but miniaturization has comes at a price. Knowing this, it seems almost megalomaniac for manufacturers to claim that their sound bars with their master both stereo and surround reproduction whilst trying to keep their regular hi-fi systems and surround systems in the picture. We're taking on the topic focusing the potential of the two top models: Bowers & Wilkins Panorama 2 and Focal dimension.

HDCP 2.2 – What You Need to Know About the Forthcoming 4K Data Security

Over the sense and senselessness of copyright protection devices can one really debate. The industry, as shown over the decades, has not tired of denouncing acts of theivery in regards to intellectual property nor has it tired of lamenting the imminent demise of an entire industry.  Many creative people feel as though they are encroached upon by such measures, patronised and placed under general suspicion. That this situation is not just here to stay but also the future -- a feeling which is shared by a coup of 100 existing industry that the Digital Protection Consortium.

Amplifiers: A Guide From Class A, Class B, Class AB to Class D

Throughout product descriptions, articles and discussions we find ourselves talking about again and again about the so-called amplifier classes which are in place to demarcate the operation of the respective circuit. But how can we really classify them? How does the ordering really work? Why are there different different classes at all? And what are the advantages and disadvantages does each bring with them? We’ve taken the best known of examokes from across the board – Classes A, B, AB and D – viewing them in more detail so that we can take this question head on.

Streaming For The Hi-Fi System – An Overview

The ongoing evolution of music shifting out of the physical sound storage medium, coupled with the way to many modes and formates of music data of storing data on your computer, laptop, smartphone or server has altered the classic job profile of hi-fi equipment. Without question, this profile can be all together further questioned thanks to the possibility of streaming entirely online, it is theoretically possible to forgo a locally-stored library all together. In response to these changes in the market, countless solutions are now available to ensure the seamless integration of the digital sphere. In addition to the special accessories there are also those products which combine what were once orginally seperate equipment categories. It's very easy to loose track, so we're going to take you through slowly, showing you several examples of components that really matter.

Digital Music: How Does It Work? Conversion After the DSD Mode

After already digging deep in the previous article with the PCM method (Pulse Code Modulation) and having quite meticulously worked through some fundamental aspects of digitisation, let's get to the much-discussed alternative DSD (Direct Stream Digital). The focus again will be mainly on the technical implementation and the resulting consequences for our digital signal. In discussing the pros and cons of one or the other format, we're here to inform – ultimately the decision is yours
