Classical Music Can Be Your Best Friend in This Political Turmoil – Research suggests that classical music could be just the thing to calm you down. Sort of like Vivaldi replacing Valium. Recent Research in Bochum, Germany had 120 participants in which half lay down in silence while the other half listened to classical music. When vital signs were taken afterwards, all had lower heart rates and other benefits, but the benefits were greatest in those who had listened to the classics. iPhones Not the Only Apple Products Dropping the Optical Out Jack for Headphones – The old MacBook Pro had an optical audio output but it is gone with the new 13-inch model, and not likely on higher-end models either. The port is described by Apple as a 3.5mm headphone jack with support for audio line out (digital/analog). There is no listing for S/PDIF optical digital audio output. Apple says “plenty of USB-C zero-latency professional peripherals are available now, or coming very soon.” Whether the MacBooks are provided with an adaptor for headphones like the new iPones is unknown. New Inexpensive LG 3D Blu-ray Deck – The PB556 is only about $166, plays Blu-rays, DVDs and CDs, has Wi-Fi […]

Benefits of a Curved Screen HDTV – Almost none. Perhaps if you’re a single person sitting right in the center of the screen it might be nice, but it prevents good viewing from the sides and takes up more room, as well as being more expensive. It may be nice in some commercial theaters but in the home the better visual quality is in fact unverified. Basically it’s just a commercial ploy to get you to spend more on a TV. And wait for the next generation of 4K HDTVs – this one doesn’t address the many other areas needing upgrading besides the resolution, and you need to sit extremely close to see any improvement in resolution anyway. And there is almost nothing reasonable available in 4K until the higher-capacity Blu-rays come out in a few months. MIT Launches Battery-Operated Headphone Amp – MIT has put their patented Multipole Technology inside an active circuit to make their Vero HCA 29 high current, silent-powered class AB headphone Amp. The new amp, which features 29 poles of articulation, is so far only on Indiegogo. Multipole Technology has been used on many films and recordings as well as MIT cables, but this is […]
