PlayStation 3 Rips SACDs – The PS3 has become the first computer able to rip SACDs with all the advantages enjoyed currently with CDs—faster than real-time copying—bit-perfect verified copies, etc. Collectors with SACD libraries can now back up their music. There are flash memories and hard drive-based DSD players from Korg, but no one has brought out a portable SACD player.  DSD—the highest-fidelity format used originally to record the best SACDs—is gaining a foothold as downloads in Japan, and will hopefully spread across the globe. It is even possible now to make surround copies, though it is limited to PCs so far and not Macs. One users stated “We need the ability to make bitperfect backups of our (hi-res) purchased music, to create a collection of music on computer easily browsed, and the ability to use the DAC of our choice.”
Samsung Doing Well in Down TV Market – Global TV shipments fell slightly in 2011, the first time they had a decline since tracking began in 2004. However, Samsung’s global flat panel TV revenue increased in the fourth quarter to 26.3%—a record for any brand. They are the market share leader in both LCD and plasma displays, and this is the first time a brand other than Panasonic led in global sales of plasma TVs. In 3D TV and LED TV shipments Samsung also led, with LG No. 2. Sony rounded out the top three but had seen an over 30% decline in revenues. 3D continues to show gains worldwide, posting them in every region including Asia Pacific. Plasma, however, fell 7% in 2011—the largest decline for that category to date.
Wi-Fi Interference Issues – are on the increase due to the explosion of wireless devices, and will only become more serious as nearly everything goes wireless. RF interference plagues many current and future 802.11 implementations. Devices don’t operate as well as expected, or in as many areas as expected, or cut out unexpectedly. It is wise to be aware of the interference and how to avoid it. Here’s a useful free page on “20 Wi-Fi Interference Myths.”  The most damaging source of RF interference seems to be 2.4 GHz wireless phones, headsets and other devices, although microwaves, Bluetooth devices and other wireless LANs can all be guilty. The advice is to use only 5.8 GHz wireless phones, but those frequencies are also going to get crowded eventually.  Some of the actions the document suggests are analyzing the potential for RF interference, preventing operation of the sources, providing strong wireless LAN coverage, setting router configuration parameters properly, and using the newer 802.11a networks.  (If the wireless device is usually in a static spot, you might try moving it or the router. I solved a cutting-out problem with my wi-fi radio that way, which probably wasn’t due to RF interference.) And remember, wired is always more reliable if possible.
