Q My current 5.1 audio setup is driven by a Marantz SR7007 AV receiver. Since I’d like to get a little more punch from it, I’m looking at upgrading to an external five-channel amp: either an Outlaw 5000 or Marantz MM7055. Here’s my question: If I connect an external amp to my Marantz receiver, will I still be able to use its Audyssey processing, or do I lose that ability? —Garry Briand / via email

Q The Rec. 2020 color gamut is the future of TV—the standard was set years ago and has been included in the specification for Ultra HD Blu-ray. Even so, UHDTVs have been around for a few years yet none can display the Rec. 2020 color gamut. Why? Are we one day going to see Rec. 2020-capable LCD and OLED TVs, or is it true that only laser projectors are capable of reproducing that gamut? —Karim Genio / Algeria, North Africa

Q I have a Samsung UN55HU7250F UHDTV that’s currently being fed by a DVD player. Here’s my question: Since the TV upscales signals to 4K, will there be a significant advantage in upgrading to a Blu-ray player if the discs I watch are all DVDs? —Patrick Tyler / Boulder, CO

Q I own a Roku streamer plus a Blu-ray player and TV with streaming apps. I'm also aware of websites for downloading "Hi-Res" audio to computers and portable players. Here’s my question: Which of these sources support surround sound music?

If you put together the thousands of SACD releases, plus releases on the DVD-Audio and Blu-Ray Audio formats, you’d think somebody should be offering streaming surround by now. I sent a question to Roku support and the answer I got was that basically "all" Roku apps support surround sound. But that sounds like a“technical capability” answer; I haven't found any content yet. —Wayne Erfling

Q I own Paradigm Monitor 11 speakers and an 80-watt powered subwoofer. The speakers are set up in my living room 6 feet out from a sliding glass door. What type of acoustic treatment product should I put up behind the speakers to improve their sound? Should it be foam or something more solid? —Jon Cotton / via e-mail

Q I am looking for a new Blu-ray player and have a question. What’s the difference between inexpensive models and ones that cost $300-plus? It seems to me that inexpensive models have as many features, if not more, than pricey ones. If it’s a question processing power or something else, does that make a huge difference in picture and sound quality? —Edwin Vela

Q I want to optimize Tidal music streaming so I get the best sound quality. But I’m a million miles away from being an audiophile and find the whole thing really confusing. Right now I stream Tidal using either my iPhone or iPad, and have a pair of Bose QC headphones. I looked into buying a headphone amp, but am unsure if such devices improve the quality of streamed music. Can you point me in the right direction? —Lee Cooper
