Yamaha's 2013 receivers get MHL compatibility

Every year AV receiver manufacturers tend to add one marquee feature to their product lines, and this year it looks like it's MHL.

Yamaha's new 2013 line of AV receivers consists of four networked models, plus the entry-level RX-V375, with the biggest change being that the four higher-end models each includes one MHL-compatible HDMI input. The RX-V775WA and RX-V675 have their MHL port on the front -- convenient for connecting a compatible smartphone -- and the RX-V575 and RX-V475 have their MHL port on the back, which is better for connecting a Roku Streaming Stick out of sight.… Read more

Toshiba SBX4250 review: A ho-hum sound bar with surprisingly good features

Choosing a sound bar largely comes down to sound quality and design, with features being far less important than when evaluating other products. That's what makes the Toshiba SBX4250 ($270 street) a bit of a hard sell: it sounds and looks just about average, but has a great feature set. There's built-in Bluetooth, for wireless audio streaming from most smartphones and tablets, plus it has a ton of inputs, with two HDMI, two optical, an analog, and a minijack. And although the sound bar itself is visually lackluster, the included remote is nicely designed.

The question is whether … Read more

Plasma TV altitude: How high can they go?

David Katzmaier and I have gotten e-mails asking a seemingly odd question: how high can plasma TVs go? These e-mails, from videophiles living in high-altitude places such as Denver and Santa Fe, are concerned plasmas either won't work for them, or will have a loud buzzing.

Turns out, they're sort of right.… Read more

Get a Logitech Harmony 700 universal remote for $59.99

This is an update of a deal I posted last summer.

Juggling is meant for circus folk, not home-theater owners. Yet that's exactly what you're doing if you have more than one device and, ergo, more than one remote.

Regular Cheapskate readers know I'm a fan of Logitech's Harmony series of universal remotes. One of the better models, the 700, has a list price of $119.99 (or used to -- it's been discontinued). Ouch.

For a limited time, and while supplies last, TigerDirect via eBay has the refurbished Harmony 700 universal remote for $59.99 shipped.… Read more
