Dolby Vision Explained 

What is Dolby Vision?

Dolby VisionTM transforms the way you experience movies, TV shows, and games with incredible brightness, contrast, and color that bring entertainment to life before your eyes. By fully leveraging the maximum potential of new cinema projection technology and new TVs' display capabilities, Dolby Vision delivers high-dynamic-range (HDR) and wide-color-gamut content. The result is a re ned, lifelike image that will make you forget you are looking at a screen.
Current consumer video delivery and cinema standards are based on the limitations of old technologies and require altering the original content before it can be reproduced for playbackdramatically reducing the range of colors, brightness, and contrast from that captured by modern cameras. Dolby Vision changes that, giving creative teams the con dence that images will be reproduced faithfully on TVs, PCs, and mobile devices that feature Dolby Vision.
Dolby Vision is a natural complement to Dolby Atmos®. It gives movie, television, and game creators the tools they need to create experiences that preserve the creative intent and let consumers experience truly immersive content without compromise.
For manufacturers of televisions, game consoles, personal computers, and mobile devices, Dolby Vision unlocks the full capabilities of their hardware and creates a premium experience that can increase use and enjoyment of these products.

What The Content Creator Is What The Viewer Gets

The limitations in today's system comes as a natural result of the limitations of current TV and Blu-ray standards. The maximum brightness for broadcast TV or Blu-ray discs
is 100 nits*. But modern TVs often have 300 to 500 nits maximum brightness, so TV manufacturers stretch the brightness of the content to try to use the capabilities of the display. This distorts the images. And because each manufacturer stretches the output differently, every viewer will experience a movie, TV show, or game in a different and unpredictable way.
Dolby Vision solves this problem. Content creators color-grade their content using Dolby Vision compatible reference monitors, which have dramatically higher dynamic range and wider color gamut, to ensure the highest- delity mastering. The Dolby Vision picture contains metadata about the system used to create the nal version
of the content. Because any Dolby Vision television has been carefully calibrated by
the manufacturer and Dolby technicians, our technology can use this metadata and the higher-quality content to produce the best and most accurate representation on every display. This honesty to the creator is why Dolby Vision is being adopted by major studios for the cinema and for delivering the best Hollywood content to the home.

* nit: In lighting, the nit is a unit of visible-light intensity, commonly used to specify the brightness of a cathode ray tube or liquid crystal display computer display. One nit is equivalent to one candela per square meter.

Major difference between the Dolvy Vision approach and other HDR solutions

A major difference between the Dolby Vision approach and other HDR solutions is the metadata that accompanies each frame of the video all the way to the display manager in the consumer-playback device. Systems with generic HDR* carry only static metadata that describes the properties of the color-grading monitor that was used to create the content and some very basic information about the brightness properties (maximum and average light levels) for the entire piece of content. Dolby Vision adds dynamic metadata that is produced during content creation; the dynamic properties of each scene are captured. With this information, the Dolby Vision display manager is able to adapt the content to the properties of the display much more accurately. It allows hues to be preserved properly, which is critical for display of skin tones. Even with mass- market edge-lit TVs, the overall impression of colors is preserved much more accurately.
Guided by the Dolby Vision metadata, the Dolby Vision display manager enables great visual experiences on a wide range of display devices ranging from higher-end OLED TVs with stunning black levels to LCD TVs with advanced technologies like quantum dot, all the way down to mass-market edge-lit TVs.
Technology has moved far beyond current imaging standards for TV and movies. This end-to-end solution delivers dramatic imaging that fully expresses the original creative intent. Dolby Vision enhances today's viewing experiences and is ready for the next wave of innovation from TV, movies, games, and streaming services

* HDR (High Dynamic Range): The contrast between the brightest whites and the darkest blacks. The high the dynamic range the closer a picture gets to real life.

 

 

Should I convert my CD collection to stored music?

Posted by Juan on 17 November 2017

After weighing up the pros and cons - I couldn't fault the idea.

Recently when visiting a good friend of mine, he insisted I take a listen to a particular track that he assured me would make his system sound even better than its remarkable looks. So off he disappeared into his CD library which covered the walls of an adjoining room like wallpaper. Upon his long awaited return and well after the last sip of my cupper and bite of Spanish torte, he victoriously waved his right hand clutching a CD jewel case. Swiftly he ejected the draw of his CD player and then. to my surprise he was nearby crying - the CD case was empty!!
After 25 years in the audio industry this is a situation I have heard many, many times.

If this has ever happened to you then I have good news - today you can convert all those bookshelves or boxes full of CDs to a Hard Disc Drive (HDD) for instant playback, all from the comfort of your listening chair and controlled from the convenience of your smart phone or tablet.

Comparing digital copies of my CD Library: do they sound better or worse?

With the right equipment, during the CD ripping process the server software has more time to read the data within than your CD player which is also tasked with simultaneously playing that data and trying to correct for any errors in real-time. Consequently, it has the luxury of being able to repeatedly re-read areas of the disc if errors are present until the data is totally accurate.

Robert Harley editor-in-Chief of the Absolute Sound magazine had this to say in his book The Complete Guide to High-End Audio;

"I've compared the sound of state-of-art CD transports to music servers playing the same music through the same digital-to-analogue converter and digital cable. I first ripped the CD to the server, put the CD in the transport, and compared the two. The sound from the server was smoother in the treble with a more delicate rendering of treble detail. The sound stage was improved when music was sourced from the server more spacious, greater image focus, increased depth, and an overall more convincing impression of instruments existing in space within the recorded acoustic. There was also a greater sense of ease and musical involvement. In short, transferring your CDs to server will improve the sound of your library."

How is it done?

There are a couple of ways to achieve this smart way of controlling and playing your music:

1. Using your home computer - Purchase a NAS (Network Attach Storage) with the capacity to hold your entire CD library. I would highly suggest a NAS with multiple mirror back-up storage, thus you will have multiple copies of your valuable music. Considering that ripping your whole CD music is going to take a great deal of time, its contents should be securely preserved - if performing just one copy it could be lost, damaged, stolen or develop a fault. Once this NAS is filled with music and connected to your home network, it can then 'serve' up your music to your (new) music streamer (see in-store for all the options). Lastly, download the appropriate app to the streaming device in question and enjoy!

2. Dedicated Music Ripper/Streamer -  Whilst utilising your computer to rip your CD collection can seem like a cost-effective solution at first, it's not without its potential downfalls. Firstly, at least an intermediate level of IT know-how is required to create your digital music collection it's a reasonably complex process. Not to mention the fact that ripping your CD collection is a deceptively time-consuming process. Secondly, the software required for the ripping process will have an impact on the quality of the end result and the accuracy of the metadata (artist/album info etc.). Lastly, computers aren't designed for quality audio data based CD drives and mechanical system noise can also affect performance.

Therefore, if you wish to ensure you do it once and do it right that's where a combined CD ripper/music streamer option is a perfect choice. Not only will you be assured of exceptional performance, but it will make creating your stored music collection much simpler and more enjoyable. Here are three highly recommended products available in-store;


BLUESOUND Vault 2 Streaming Player

The Vault 2's 2TB hard drive will let you rapidly rip all your CDs in lossless high-resolution as well as download and store high-resolution tracks.

AUDIO SCEPTICISM - ON TEST

Posted by Juan on 8 November 2017
AUDIO SCEPTICISM - ON TEST

LES DAVIS AUDIO 3D-2 Constrained Layer Dampers

Would you believe that a few discs, 50mm in diameter and each less than a millimetre thick can make a substantial audio improvement on any Turntable? And not just your turntable audible improvements can be heard on each component of your system thanks to the deceptively simple Len Davis Audio 3D(2) Discs.

Mechanical Resonance is a phenomenon in which an object or system is subjected to an oscillating force with a frequency close to its own natural resonant frequency. These added frequencies combined with the playback frequencies stored in the record groove then colour and add murkiness to the sound. Therefore, eliminating these resonances (or at least greatly diminishing them) can significantly improve the sonic performance of your audio system. Enter the 3D(2), a new product with advanced technology that promises to do exactly that.

The 3D(2) is designed and manufactured in Australia and has been developed by Les Davis over the last ten years. The 3D(2) discs are a composite layering of an industrial grade soft aluminium foil constraining layer and a pressure-sensitive viscoelastic polymer. This constrained layer damping (CLD) is what promises to suppress unwanted vibrations. It's worth pointing out that there are many products marketed for vibrational control in hi-fi. However, the 3D(2) is something quite different. Not least for their affordability. Each box contains 16 feet. To install them, they're simply placed in a stacked pair (for the optimum performance according to Les' highly-trained ears) under each foot of your CD player, amplifier, pre-amp, power supply, turntable, etc. So, typically, a box will treat an amp and a CD player for example. With speakers you can use it under the feet of a stand, but you need to be careful. It can be too much of a good thing, according to Les. Interestingly, there's even a new loudspeaker being developed by legendary Australian speaker designer Brad Serhan that utilises the same 3D(2) technology as a gasket to seal the drivers to the front fascia, resulting in dramatically reduced cabinet vibrations. Intrigued, I decided to put them to the test.

Sceptical at first thanks to the 3D(2)'s unassuming size and deceptive looks, I commenced the listening session with some vinyl curtesy of iconic Australian modern jazz artist Vince Jones, spinning via the Pro-Ject 2Xpression turntable (see below for full equipment list). For the control test, I started with opening track For All Colours from the album of the same name. Then, another pass through, this time with the 3D(2) dampers placed under the Pro-Ject 2Xpression. No sooner had the needle hit the groove when the immediate improvement hit my ears. Beautiful detail and clarity of instruments and voices, Improved imaging, cleaner soundstage - all culminating in an easier appreciation of the size of the musical presentation and allowing me to better envisage the instrumentalists and vocalists. Then, a moment of realisation; Listen to how much I've been missing before this test! Or to put it another way, so much of our music enjoyment has been taken away...

Conclusion: If you are (or even if you're not) an audio sceptic, I would highly recommend listening to the 3D(2) Discs. There's a very good chance you will become a true believer!  

This amazing product sells for only $99 and is available instore now!

Our Three Part Guide to an Affordable, Future-Proof High Fidelity System - Part 3

Posted by Juan on 23 October 2017
Vinyl: the retro-cool factor
LP's deliver a true to life performance often unmatched by standard-resolution digital audio.
If you haven't had the opportunity to experience a good LP playback system, I'd encourage you to pay us a visit and ask our staff to playback a record for you. There's even a good chance that you'll find music you like within our LP collection.

How much should you spend in a turntable? You should dedicate a greater proportion of your budget on the components you spend more time listening to. If you're fortunate enough to have a large collection of vinyl that you play daily and consider them your primary source of music, you should consider as well that the turntable will be your system's front-end. No system can compensate for poor information acquired at the front-end, so, aim for the highest performance turntable you can by investing about 35-40% of your budget on it. Conversely, if most of your favourite music is on CD or your primarily streaming music in standard or hi-res music and your turntable is going to be more of a secondary source, that figure could be around 15% of your budget.

CD & Digital music: Kings of Convenience
Your system front-end, in this case, will be your CD player, or your Music Streamer. If you have a lifetime collection of CD music, same will apply as per the previous paragraph: you should dedicate a greater proportion of your budget, on the components, you spend more time listening to, but we may be more conservative in this case suggesting about 30 to 35% of your budget.
The Music Streamer solution can deliver digital music to your system in varying performance levels; from less than CD quality, to CD quality, all the way up to high-resolution 24bit depending on the capability of your music streamer, and the online music provider you select. Of course, your own CD collection can also be streamed. One such solution is to rip and store your CD collection a network storage device, making your collection available through your home network to be seen by a streaming device connected to your hi-fi system. We will explore in depth in the next article "Music Streamers: what they do, should you need one, and what is available".

Our Three Part Guide to an Affordable, Future-Proof High Fidelity System - Part 2

Posted by Juan on 12 October 2017
Loudspeakers

Speaker designer Andrew Jones is the master of creating award-winning speakers with remarkable sound quality and on a small budget. Well known for his work with KEF, Infinity and Pioneer/TAD, he has most recently created a whole new range of amazingly affordable loudspeakers and electronics - this time under the umbrella of hi-end German speaker manufacturer ELAC. The aim; to bring audiophile quality to the masses.

Andrew caused a sensation at T.H.E. Show Newport Beach 2015 where people were delirious about his new ELAC Debut models - even Herb Reichert from Stereophile magazine was impressed.

Andrew's later creations - the ELAC Debut B5 and Debut B6 have been met with glowing praise from critical music listeners and reviewers alike - and I can understand why after a recent listening session pitting the Debut B6 up against several speakers, some of them with price tags more than double the price of the B6.   

Listening to Vince Jones's For All Colours (streamed via Tidal thanks to the BluOS MDC module fitted to the NAD C368) on the B6, I could recreate in part the spaciousness, resonances and liveliness I heard from experiencing Vince Jones and his bands live performance at Lizotte's theatre in Lambton, Newcastle last September, reminding me of how moved and privileged I felt listening live to one of the great legends of modern Jazz music. 

The B6 delivers the bass and punch required for conveying the high dynamic effect of the drums, trumpet, double bass, and piano typically found in such jazz recordings - performance qualities that can be extended to all music types. Therefore, after hours of audition and comparisons of speakers, the Debut B6 is truly deserving of a place in any "Affordable Audiophile quality" system.

TIP: As we go to press, those happy to spend a little more might also audition the floor standing Richter Jaguar. At a heavily reduced price limited to the last few pairs, you can add that extra level of bass impact that would suit larger size rooms.
