THE VERDICT
The DAP-1520 provides a simple and inexpensive way to improve spotty Wi-Fi coverage and set the stage for improved streaming.

Tell me you haven’t had to deal with Wi-Fi drop-outs when you move to the outermost regions of your humble abode with a laptop or tablet in tow? You know, the old 4-3-2-1-0 bar shuffle… I got so fed up with fighting to hold onto the signal from the sofa in my family room that I planned to move my router to a more central location. It sits in my basement office at one end of the house, admittedly, about as far away from central as you can get. But when I thought about having to snake wires across joists and up through the floor, I decided to find another solution—a quick fix, if one existed.

A Do-It-All Processor, At a Price

Steinway Lyngdorf P200 Surround Processor

At last September’s CEDIA Expo, Steinway Lyngdorf offered a sneak peek of the P200 surround processor it plans to start selling in early 2015 for $18,000. (No, that’s not a typo.) The P200 distinguished itself as the first processor to support both Dolby Atmos and Auro-3D. Equipped to handle multiple speaker setups, it’s designed to switch between speakers positioned for either format at the touch of a button. To get the story behind this one-of-a-kind product, we spoke with CEO/CTO Thomas Birkelund.

Stereo Is Father to the Surround: Al Kooper Talks 5.1

Al Kooper has been a mastermind behind the board of many a storied session over his half-century career, but his prowess as a multichannel mixmaster has been largely unheard — until now. Audiophile circles have long been well aware that Kooper had turned in “interesting” 5.1 mixes to Sony for a pair of albums he personally had stakes in — Blood, Sweat & Tears’ trippy big-band-influenced debut, Child Is Father to the Man (originally released in February 1968) and Mike Bloomfield, Al Kooper, and Steve Stills’ still influential jam amalgamation, Super Session (July 1968). Both mixes gathered multichannel dust on the corporate shelves until almost a full decade later, when Audio Fidelity released them from captivity by way of a pair of Hybrid Mulitchannel SACDs. Here, Kooper, 71, and I discuss his surround mixing philosophy for both of those classic releases, why he’s not a fan of mono or streaming, and his alternate, Bloomfield-centric mix of Bob Dylan’s “Like a Rolling Stone” (on which Kooper played the infamous improvised organ riffs). There are no longer any 5.1 secrets to conceal.

IR or Not, These Apple Apps and Devices Put You in Control of the Remote

It’s rare to be able to mention a feature that’s found on an Android device that wasn’t featured first on an iPhone, probably with a sleeker presentation. Somehow, however, IR remote control ability seems to have been left out of iPhones, even though it was rumored to be included on the iPhone 6. Samsung, LG and HTC all have managed to include IR blasters on their phones, yet Apple devotees have been out of luck if the want to control their home theaters, until now.

Homeworld Remastered

After the implosion of THQ and the rights to the game bouncing from publisher to publisher, Gearbox studios picked it up and ran with it.

We’ll, sort of. Instead of making a new game, Gearbox took the original Homeworld, and updated the graphics.

This is 100% fine by me. Here’s the deal…

I'm genuinely curious so please don't take this as a trolling attempt:

To the best of my knowledge an amplifier's function is to take a weak (source) signal, amplify it, and pass it on. Now, if that's the case, how on earth can one amplifier improve (or even just impact) imaging better than any other amplifier in any other way than applying more or less power?

Willie...thanks for the question. Every amplifier has its own signature sound, depending on the topology used in the electronic path. Some do it much better than others, that's for sure, but a "bad" amplifier will introduce noise and distortion into the signal that will get "amplified" with a higher output. Throw in a week power supply/transformer and you have a poor performer. If the design is done right, like this one here, you get a very clean rendition of the original signal. Does that make sense?
