Sound Advice: Technics EAH-AZ70W true wireless earphones put comparably priced competitors to shame

Amazing earphones that I could not wait to tell you about: To start us off this week I will take your back to December 2017 when I wrote about the Technics Ottava SC-C70 Premium All-In-One Music System with integrated CD player. When I first saw, touched and heard the SC-C70 I thought it would sell for $3,000 to $5,000 given the amazing sound, ...Read more

Sound Advice: Soundcore Rave Neo sturdy, waterproof speaker

Q. Can you recommend a pair of outdoor Bluetooth speakers for a patio? The patio is 20-by-32 feet and the speakers need to have an internal battery since there is limited access to electrical outlets. They should be water-resistant and we don't want to put a lot of money into them in case they "somehow" disappear. Of course, we would like good ...Read more

Sound Advice: Specialized audio furniture makes a big difference

Q. We are really enjoying our new stereo composed of Polk LSiM 705 speakers, Cambridge Audio Alva turntable, Cambridge Audio AXC35 Stereo CD Player and Cambridge Audio CXA80 amplifier.

Sound Advice: Stereo receivers provide more real-world power than audio/video receivers

Q. Currently I use a home theater receiver for my system and need an affordable, good quality stereo receiver to replace it. My receiver is running very hot trying to power two pairs of 8-ohm speakers (one indoor pair and one outdoor pair) and it just doesn't sound good overall. In addition to the speakers I have a Cambridge SoundWorks BassCube ...Read more

Sound Advice: Panasonic LUMIX FZ1000 Mk. II camera a delight

Q. I have a Nikon D5100 DSLR and would like to get a longer lens for wildlife and landscapes. I was looking at the Nikkor 24-300mm FX lens but don't know how it would pair with the D5100, which is a DX camera body. What about the Sony RX10 IV camera as an alternative? It has a fixed 24-600mm zoom lens with a 20 megapixel, 1-inch sensor. How do ...Read more

Sound Advice: Denon DRA-800H recommended full-featured HDMI stereo receiver

Q. I haven't spent any money on stereo equipment for what seems like forever! I find myself listening to Pandora through my TV, but I would like to set up a stereo system. I have a pretty decent number of vinyl records and would like to listen to the TV through the stereo if possible.

Rather than listen to music through the TV, is there a ...Read more

Sound Advice: TVs today not known for their outstanding tuners

Q. We do not have cable and use a roof-mounted, medium-sized antenna to receive TV broadcasts. The picture on our 32-inch Insignia breaks up and freezes when it is windy. The TV has a few other issues so we are going to replace it. What TV has the best over-the-air tuner for receiving broadcasts? We would like a 43-inch screen and can spend up ...Read more

Sound Advice: Upgrading turntable offers bigger audio boost than improving CD player

Q. I recently took advantage of Emotiva's "30% back in Emobucks" promotion and bought the $399 T-Zero speakers. I then used the resulting 30% credit towards their $399 TA-100 receiver. Now I want to get a turntable and upgrade my CD player, which is an old Technics SL-PG100 from the 1990s. I have $1,000 total to spend and figured I would spend $...Read more

Sound Advice: 8-Series is TCL's best television

I went to their website to order and to my surprise the price was $1,249.99 with free delivery, reduced from $1,999.99. It will be delivered this week and needless to say, I am very happy with this deal! Do ...Read more

Q. Do you have a wireless subwoofer recommendation? I'm hoping to find one under $400, with reliable wireless connectivity and solid performance.

-- R.P., Pleasanton, Calif.

A. I prefer to avoid subwoofers with built-in wireless unless it is part of a package like a soundbar with a wireless subwoofer. You can use an adapter to make almost any ...Read more

Sound Advice: Polk Audio Legend series bookshelf speakers highly recommended

Q. My husband has large planar speakers (6 feet high, 3 feet wide) and we are moving to a condo. It will be impossible to use them in the smaller space. Can you suggest small speakers that would provide the same quality when he plays his classical records? We are willing to spend up to $3,000 total for the speakers and amplifier.

-- C.S., ...Read more
