ASK S&V

Q I was planning to replace my 225Wpc Anthem Statement A2 amplifier with a 300Wpc McIntosh MC302 amp to improve my system. It was suggested that I would get more bang-for-the-buck by instead replacing my Integra DHC 80.3 surround preamp/processor with a new McIntosh MX122 surround preamp/processor. The reason given was that upgrading to a marginally more powerful amp wouldn’t result in a significant difference in my system, but a state-of-the-art processor would. Do you agree with that viewpoint? The speakers I am using are Definitive Technology Mythos STS Super Towers with a Mythos center channel and surrounds. — KJ King

Q I just bought an Apple TV 4K streaming box and was wondering if I can use it with my surround sound system. If so, how do I connect it? —Mario Caballero

A I’m interested in buying a new Ultra HD Blu-ray player but don’t yet own a 4K TV due to budget constraints. Can an Ultra HD Blu-ray Disc be played on a regular HDTV? What quality issues would I run into? —Billy Keener / via e-mail

Q I currently use dipole speakers as the side surrounds in a 7.1-channel configuration. My plan is to upgrade to an Atmos setup and replace the side surround speakers with direct-radiating models. Here’s my question: Could I use my existing dipole surrounds as Atmos height speakers? —Nick Ward / via e-mail

Q After a lull of many years, I’m now in the market for a new audio system and plan to buy high-quality tower speakers and a good amplifier. Here’s my question: How do I deliver an audio signal to passive speakers using just an amp and no preamp or receiver? I’ve become accustomed to the convenience of music-streaming apps like Pandora and don’t want my new system to be unnecessarily complicated. —Gary Barnett / via e-mail

Q I was recently in Best Buy asking about speakers for Dolby Atmos. I was told that to get Atmos I would have to change out my current setup and buy a new set of Atmos Speakers. Is that true? —Wendell Blue

A I own a Panasonic plasma TV and a Denon AV receiver. When I connect my sources directly to the TV, the picture looks great. But when I run my Oppo BDP-105 Blu-ray player, cable TV box, and Amazon Fire TV media player through the Denon using HDMI cables, the picture quality degrades. Is there a way I can work around the picture quality problems caused by my AVR? I want to continue using the AVR for audio switching and prefer to not have to connect sources directly to the TV. —Henry Yeboah / via e-mail
