Larry has 12-year-old florescent backlit TV and it's time to upgrade to 4K. It's in a surround sound system with a Denon receiver and he would rather not upgrade that as well. Leo says there is an "upgrade cascade" that happens when there is a home theater system. If an AV system drives video, then users have to upgrade it. But if it's just running the audio, they'll be fine. Just use the optical out on a new TV. Upgrade the ROKU box to 4K capable. But what's even more important is the HDR support 4K brings.
Steve is looking to buy a refurbished Yamaha receiver. Leo says that refurbished devices are best bought from the original manufacturer. That way he can still get a warranty to go with it. All too often, they are brand new devices that were returned, and as such, can't be resold as new. So they're sold as refurbished instead. If he's looking for a great deal, refurbished is the way to go. He should just make sure to get it from the original manufacturer.
Steve had heard that Leo likes Onkyo receivers, and now is wondering what features he should make sure it has: Airplay? Bluetooth? Pandora? Leo says he doesn't really use any of that. It's far easier to use his smartphone for some of those features. The processors are slow for those things anyway. Steve should go with the Roku or his Internet enabled TV to do those things. One feature he liked is the number of HDMI inputs -- the more the better. Should he get a 4K TV? Leo says not right now. It's coming, and it'll be great. But it's way too early in the game to invest in a 4K TV.
Adam is looking to get a new LG 5500, but it only has two HDMI ports? Leo says that budget HDTVs usually only have a couple of HDMI ports. He recommends that if you need more, to get an A/V receiver like the Onkyo 616, which includes 7 HDMI ins, and Denon makes a great one as well.
Scott Wilkinson went to see The Hobbit last night, not only in HFR, but also in Atmos. Sadly though, the projector crashed and he couldn't see it. Leo says that digital projectors are just computers and sometimes, they crash. The great irony is that it was a special screening of media by Dolby for the HFR and Atmos presentation. And the great irony is, that while there was a Dolby tech there to handle any Atmos issues, there was no projector tech.
Scott Wilkinson is back with some questions: Ian has 8 ohm speakers and 6 Ohm speakers and wants to know if he can get a receiver that can handle both of them? Ohm pertains to “impedance,” which is resistance to the alternating current of an audio signal. Resistance is important because it prevents speakers from being blown out. The lower the OHM number, the greater the power drawn out of the receiver to the speaker. Onkyo, Denon or Pioneer are probably the best makers of an amp for that combination of speakers.
