Riva Audio introduced a line of wireless multiroom speakers designed to deliver larger-than-life, live concert-style sound at its coming out party at CEDIA 2016 . Two of those speakers, the $249 Arena and $499 Festival, should be shipping in March. A new product the company has on display here at CES is the Theaterbar soundbar.

Audiophiles have many portable playback options, including compact high-performance DACs and serious headphones, to choose from. But what about high-quality video on a phone?

Best known for its affordable TVs with built-in Roku streaming capability, TCL is showing three new UHDTV lineups at CES, including the company’s top-of-the-line P Series sets.

Q I’m using a Marantz SR5005 AV receiver rated at 100 watts per channel to power a 7.1 speaker system. My surrounds sound like they’re getting enough power, but I’d like to add three external 200-watt monoblock amps to increase output to the front left, center, and right channels. Here’s my question: Will the receiver’s Audyssey MultEQ automated setup calibrate the system in a way that accommodates the added power? In other words, will I still get full power from the front three channels if I use external amps and Audyssey MultEQ? —Todd Hunt / via email
