Ask S&V

Q I recently purchased a Bose SoundTouch 130 soundbar and have a Samsung BDP7500 Blu-ray player connected to it. Here’s my question: There’s a setting in the Samsung player’s menu for speaker size and distance. Since I’m using a soundbar that gets calibrated using a headset in five positions, is it necessary to also adjust the Blu-ray player’s speaker size/distance settings, or should I just leave those alone? I called Bose tech support, and they had no answer for me. —Peter Palagonia/Las Vegas, NV

Q I have a Denon A/V receiver hooked up to a 5.1-channel speaker system. The setup works fine for movies, but every now and then I want to listen to good ol’ stereo recordings ( I have a modest collection of CDs stored as Apple lossless audio files).  I am tempted to purchase a high-end integrated amp for just this purpose. Which gets me to my question: Can I hook both my receiver and the integrated amp to my front L/R speakers? —Nick Gruin

Q In a picture accompanying S&V’s recent article on VIZIO’s Reference UHDTV, I noticed a coaxial cable input on the back panel next to the HDMI connections.  This made me wonder why coaxial cable is used to convey over-the-air and cable HD signals, but HDMI connections are used to carry them the last six feet to our screens. Is the issue copy protection in the HDMI cable?  Or is it about compression/decompression? —Ben Hurwitz / Greensboro, NC

If there’s one thing we know for sure about an Ultra HD broadcast standard, it’s that its still under development. But will TV stations really end up broadcasting 4K-resolution programming? Will the average viewer even care?

LG made a bold statement with its Signature model and other OLED TVs at CES, but it isn’t the only company hawking the technology. A surprisingly small A/V product showcase in Panasonic’s booth featured the company’s forthcoming 65CZ950 OLED UHDTV.

Buried deep in the Mobility zone of the LVCC’s North Hall, Libratone’s minimalist wood and glass-lined booth seemed an oasis of Scandinavian design amidst the electronic(s) noise.

Dynaudio’s first- and second-gen Xeo wireless speakers were previously reviewed in Sound & Vision. Long story short, we liked ‘em. Now the company has a new wireless speaker, the Xeo 2, that adds a few features the previous versions lacked, and is also considerably more affordable.
