Q: What would you recommend for a 5.1-channel surround-sound system using very small, wall-mountable speakers and a receiver? I would like to spend up to $1,000, and the most important factor is to get the best sound quality I can.

A: You can get very good sound with your budget, though extremely small speakers do have sound quality limitations. This is because their woofers cannot move enough air to produce the midrange fullness and depth you hear in larger speakers. It is most noticeable when you listen to music.

If you want very tiny speakers, a combination that has never failed to please me is the $499 Definitive Technology ProCinema 400 speaker system paired with a Marantz 5.1-channel receiver. I have seen the Marantz NR1504 on clearance on Amazon for $299, and the company's model 1506 is $499. The sound quality is identical, and the difference is primarily in wireless features. I'd get the NR1504 for $299 and add a $20 Bluetooth module, saving $180 in the process. The ProCinema 400 includes a subwoofer, so all you need is speaker wire and a subwoofer cable, and you are good to go.

If you can stretch your budget a bit, upgrade the speakers to the $999 SVS Prime Satellite 5.1 system. This will take performance up several orders of magnitude for both movies and music. The Prime Satellite system has met with universal acclaim, and I have been impressed every time I have heard it. The speakers use a 4-inch woofer that has a much bigger, fuller sound than any teacup-sized speaker.

SVS also has some of the best warranty and satisfaction policies in the business. You can try the system in your home, and if you are not satisfied, you can return it for a refund — and they will even pay for return shipping. That is as risk-free as it gets, though I can't imagine many people would want to return the system. SVS also has an online outlet store if you want to save money and get closer to your suggested $1,000 budget. As with the ProCinema, all you need is speaker wire and a subwoofer cable.

Color coding

Q: You recently recommended the Onkyo DX-C390 CD changer. What is the difference between the DX-C390 and the DX-C390B?

A: The B is for the color, in this case black. Many components are available in both black and silver finish, although today the trend is mostly black. It seems to swing back and forth every decade or so — black is in style, then silver, then back again. When you see a B or S at the end of a model or product number, it almost always means black or silver finish.

Lots of CES highlights

I recently returned from the 2017 Consumer Electronics Show in Las Vegas. I saw lots of noteworthy products selling from under $50 to more than $50,000.

Three things that caught my attention: Midcentury modern styling everywhere, turntables on display around every corner and Amazon's Alexa voice control spreading across many different products in many different categories.

There were also some great new digital cameras, too, and an incredibly beautiful OLED TV that is so thin it looks like a patch of wallpaper stuck on the wall. Look forward to lots of neat stuff in my column and on my website in the weeks to come.
