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

Q My Yamaha RX-A2010 A/V receiver is connected to a Samsung 4K TV, Verizon HD set-top box, and Oppo Blu-ray Disc player. Here’s my question: Is it possible for me to watch a baseball game while listening to music? Whenever I play music from a turntable or other audio source, I’m not able to see video on the screen. What am I doing wrong? —J. Rivera / via e-mail

Q I’m planning to replace my 20-year-old receiver and would like to hook up older components including a laserdisc player, cassette deck, VCR, and turntable. I like Yamaha and Denon receivers, but I’m confused about the connection options. My newer gear consists of a Samsung HDTV, Oppo Blu-ray player, Roku 3 media streamer, and Verizon Fios HD set-top box. —Dan White / via e-mail

Q I’ve noticed that almost every low/mid-priced (under $700) AVR that Sound&Vision has reviewed recently lacks a phono input. With the recent resurgence of LPs, it’s annoying to think that one would have to spend more money to hook up an external phono preamp when in the old days every receiver had one.

I know that HDMI and wireless inputs are all the rage, but don’t want to spend $500 on a receiver plus another $50-150 for a phono preamp, just to listen to my LPs. Are there any reasonably priced AVRs available that have a built-in phono preamp, or should I bite the bullet and buy an external phono preamp for my current receiver? If the answer is the latter, could you suggest a good model for under $100? —Tim Marlow

Q Most multichannel speaker configurations I see advertised have large L/R tower speakers combined with smaller center and surround speakers. It seems to me, however, that money invested in large (mostly full-range) L/R towers would be wasted if you care more about multichannel movie soundtracks than two-channel stereo music. Given the conventional wisdom that movie soundtracks rely heavily on the center channel for dialogue reproduction, shouldn’t you buy a higher-performing center speaker instead of big front towers? —Rick James Boettger / via e-mail

Q The foam surround on my Velodyne f-1200 subwoofer has disintegrated. I wanted to have it repaired with a rubber surround, but the guy at the speaker repair shop advised against that. Is there any benefit to using foam instead of a rubber surround when repairing a subwoofer driver? —Pete Gibson / via e-mail

Q I want to upgrade my receiver but have been out of the loop for a few years. My budget is $1,000. What I am looking for is to get surround sound in my TV room and also power a pair of outdoor speakers. Is there a receiver that will let me play music outside and adjust everything while simultaneously getting surround sound in my TV room? Or do I need a two-receiver setup for that? --Mike Mulhall

Q I have 6 pairs of speakers spread throughout my house that are powered by a Rotel RB-1080 stereo amp. I use a Rotel RSS-900 speaker selector box to feed each speaker pair, and there’s a wall-mounted volume control in each room. The setup works good overall, but doesn’t sound that great.

I’d like to upgrade my system with a multichannel amp, but can’t find one that A) has at least 100 watts per channel, and B) has banana plug connections. I’m willing to spend a few thousand on the upgrade, so price isn’t an issue. Do you have a few amps you can suggest that meet my requirements? —Rob Green via email

Q How would I go about setting up multiple surround speakers in the same channel—two side left and two side right speakers, for example—as in a commercial movie theater? One more question: If I used a Y splitter and additional amplifiers to power the speakers, could I still employ Audyssey processing to calibrate the speakers? I am planning to build a home theater with two to three rows of seating. —William Lee / via e-mail

Q I’m shopping for an outdoor speaker to use on my back patio and was leaning toward Sonos. Here are my questions: Can I stream audio to Sonos speakers via Bluetooth from my iPhone? Also, are Sonos speakers able to both play tracks from my computer’s iTunes library and stream them from Apple Music? —Jim Flynn

Q I have read that the electrolytic capacitors in audio equipment can degrade and leak after years of use and that sound quality will suffer as a result. Is this true? I have a few pieces of 25-to-30-year-old gear that still sound fine to me. I’ve also read that upgrading capacitors can improve sound quality. Is that another myth? —Rob Gerry / via e-mail

Q Is it true that bigger TV screens -- ones in the 65-inch and above range -- have more noticeable pixelation? --Rufino Mendoza

Q My girlfriend and I want to watch movies and listen to music late at night without waking up everyone else in the house. Here are my questions: Is there is a proper way to drive two pairs of headphones from the same amplifier without degrading the signal? Is it as easy as using a jack splitter? We care about great sound, so I'm planning to use HifiMAN, Audeze or Oppo open back headphones, but I'm wondering if I can get away with using only one amp (either a dedicated headphone amp or my home theater receiver). —Raphaël Rainville / Montreal, QC, Canada
