The High End of Sound with California Audio Technology



California Audio Technology, known as CAT, work with third-party hardware vendors in the home theater field to produce some of the best sound quality available.  They were recently at the Consumer Electronics Show in Las Vegas showing off their latest top-of-the-line 2 channel audio speakers.  These aren’t speakers for the feint of heart.  Each tower weighs in at 120 pounds.

CAT makes more than simple tower speakers though, they precision-make each speaker and can design them for almost any installation, including hidden in-wall speakers.  Their custom-made speakers can be found anywhere from homes, to music studios, to mega yachts.  All of that massive weight comes in handy to prevent any speaker vibration, which is a common issue in cheap speakers.

To really understand everything that goes into these speakers you will really need to watch the video below for an in-depth explanation of how they are milled and how they work.  You can visit them at their web site.  CAT speakers are on the market now, but if you have to ask the price….well, you know how that saying ends.

Cambridge Audio DacMagic Plus and StreamMagic 6



Cambridge Audio LogoI think it would be fair to say that Cambridge Audio has successfully moved from being a budget hi-fi brand into a solid middle tier player with several of their products receiving praise from audio and home cinema magazines. Consequently, I was interested to see what Cambridge Audio was demonstrating at CES this year, especially as it’s a British company. Scott has the interview.

The DacMagic Plus is a digital-to-analogue converter that will take the digital output from a games console, PC or smartphone, analyse and upscale the signal and then produce a clean analogue signal vastly superior to that produced by the original device. Let’s be honest, the DAC in your average games console or PC probably cost pennies to the OEM so it’s unlikely to be hi-fi quality. The DacMagic Plus has a pair of digital inputs, both optical and co-axial, plus USB input for high data rates (24 bit). There’s also an optional Bluetooth adaptor which uses the new AptX high quality codec. Output is to headphones, phono (RCA) and XLR.

The StreamMagic 6 is a new network music player that streams from a wide variety of sources – PC, uPnP, DLNA, Internet radio, Pandora – and it connects to the network either by ethernet or wireless-n. Cambridge Audio provides an on-line music portal which lets the audiophile choose their listening selection from a PC or tablet before sending the playlist to the StreamMagic. This neatly avoids the problem of poking around thousands of tracks on a tiny screen trying to find the ones you want. Round the back, like the DacMagic Plus, two digital inputs can take signals from sources such as smartphones or music players.

Overall, two great products that are definitely worth checking out.

Sony Wireless 7.1ch Headphones



Sony in the UK have announced the MDR‑DS6500 digital wireless 7.1ch surround sound headphones. That’s quite a collection of adjectives, so to break it down into the constituent parts…

Digital wireless – All-digital wireless transmission resists noise and interference from other devices in the home. Automatic tuning switches seamlessly between RF channels in the 2.408 – 2.473 GHz range to optimise signal reception. Range approximately 100 m so you can roam your home while listening to you tunes.

7.1ch – Exclusive to Sony, Virtualphones Technology (VPT) reproduces the soundstage of multi-channel speakers. Even if you’re listening to a stereo 2ch or 5.1 channel programme, VPT builds a virtual 7.1 channel stage that stretches behind and beyond the screen. There’s also a choice of selectable surround sound modes to optimise listening for movies, gaming or speech.

Surround sound – Supporting Dolby Digital, Dolby Pro Logic IIx, DTS and DTS ES, the base station will take both digital optical and analogue inputs.

Headphones – Over the ear, weighing in at 320g. Pretty good looking too. When they’re not being used, you can rest the MDR‑DS6500 headphones on their wireless charging dock. Three hours charging time provides power for approx 20 hours listening time.

Available in May for a £249. Not cheap. Full specs here too.
