The Yamaha RX-A2040 is a powerful AV receiver that features Dolby Atmos, nine channels of amplification and two HDMI outputs that can be assigned for multiple zones in a whole house audio system, and streaming audio from Pandora, Spotify, or your DLNA Home Network. We spent several months with...

Well actually I try to appeal to all audiences but every now and then I like to test drive a Porsche or the Lexus LFA instead of just driving a Civic ;) As you know, we always preach multiple subs so we are on the same page. I just don't like seeing junk parts put in expensive or...

We were able to get a look at Pioneer’s Elite VSX-45 and VSX-90 receivers today and were pleased with what we saw. With these new receivers being 4k video ready and having networking features like Bluetooth and Wi-Fi as well as interface upgrades they're loaded with features to modernize your...

While I can understand designing a good speaker in a tight budget is challenging, I honestly don't understand how it's possible to build a poor speaker in today's age with such excellent drivers, simulation software, etc. Let's forget the silly designs like placing tweeters on opposite ends of...

The Denon HEOS Drive fills a gap in the multi-room audio market that has been ignored for years. A great balance between the ease of set up and operation consumers demand, and the flexibility custom installers need, the Drive hits a sweet spot. At $2,499, this 4-zone amplifier sports a host of...

Thanks Floyd. Oscilloscopes are not good devices for seeing distortion until the distortion levels are too high (you only get about 40db resolution on an analog scope or 1%). I would think a multi-tone test as you suggested would be the way to go. Perhaps something like Don Keele developed...

Damn that Kim Jong Un. He honeydicked us. We will get him back.

Yes but the industry needs to sell new and more!

Audioquest’s relatively new device– the DragonFly USB DAC v1.2 offers a great portable way to improve your current computer and smartphone set up. With a flair in creating affordable mid-fi products, Audioquest have not failed to satisfy the market with an outstanding hi-fi sound. The USB DAC...

Guys I was just told by Outlaw that they are running a Fathers Day sale for $579 FREE Shipping on this sub. That's one heck of a deal and a great gift for ALL dads :)

Great post please share the other research on audible distortion you've found. We are actually working on an article regarding perceived distortion in speakers/subs so I'd like to see this info. The problem with distortion tests I'm seeing now is the simple distortion sweeps done at the NRC...

Soundstage only does a portion of what Floyd talks about in this article. Also NOBODY is properly measuring loudspeaker distortion and correlating it to what we hear. CEA 2010 testing is the closest thing but it's being used primarily for subwoofers. We have quite a way to go but the Harman...

I have 2 business machines here with notices for Windows 10 upgrade. I'm also skeptical about doing this as I will be crippled if the upgrade hoses my computers. Also, I'm still running Office 2007. Is it even compatible with Windows 10?

Accurately measuring loudspeaker performance is pretty much a universal problem among most loudspeaker manufacturers and ALL AV review publications. Harman on the other hand under the guidance of Dr. Floyd Toole and Sean Olive have developed a purely scientific methodology that actually allows...

As soon as you mentioned a cable causing an amp to go unstable, I thought of Goertz. Sandwiching flat conductors results in very low inductance at the expense of very high capacitance. Not a good idea. I did measure and write about this cable over a decade ago...

Outlaw Audio decided that it was time to evaluate their line of high performance subwoofers and wondered what could be done to design a better product. After a year of research and design the new Ultra-X12 Subwoofer was released. By combining the best that their LFM1-EX and LFM-1 Plus...

The EMPs are a good overall sounding speaker that play very loud and clean but they don't have much bass below 50Hz. Coupled with a nice sub, you will get fullrange sound so it's a good investment to get that sub when you can.

The R55s are relatively easy load to drive. Save your money, get the S501 and add a sub down the road to increase bass extension below 50Hz. A small ported 10" sub will really do wonders to this system more so than a beefier amp.

In our recently added YouTube video we discuss room acoustics and the importance of balancing the sound in your room to get the best possible performance from your speakers. Over treating can make your listening space sound too dead and take the life out of the room. Too little treatment can...

I like it. You may be on to something. BTW we just put up a very basic video on Room Acoustics and plugged a certain book you may be familiar with. Have a look when you can.
