Hitachi's drive division has established a beachhead among thrift-conscious media professionals with it's G-Tech line. The long-awaited G-Connect, however, is a vastly different type of product - a portable wireless media server, meant for the iOS accessory market. It's a cool little box, packed with features.

But what, exactly, is this thing? And who is it for?

While there are multiple ways to get TV programming — broadcast, cable, satellite, telco (Verizon FiOS/AT&T U-verse), or over the Internet — I’ve received mine via cable for as long as I’ve been a member of the TV-consuming public.

We've long been fans of CEntrance's portable USB DAC/headphone amp, the DACport; in an expanding market of bus-powered USB DACs, the venerable unit (along with its streamlined sibling, the DACport LX) remains a favorite of, and reference for, many reviewers of portable audio gear. Now they've gone ahead and put out a complete two channel system, of all things - the Audiophile Desktop System.

There’s some debate among vinylphiles about whether USB phono preamps need to exist, but I for one am glad they do. When I bring home my latest haul of vinyl from Amoeba Records, I love being able to plug a laptop straight into my NAD PP 3 to make quick MP3s of albums I like so I can listen to them on my smartphone. (Sacrilege!) It’s easier than making an analog connection, and it bypasses the lousy analog-to-digital converter built into my laptop.

With the Zphono-USB, Parasound brings new versatility and features to the USB phono pre concept.

Aah, summertime. Lather on sunscreen, pump up the bike tires, and you’re almost set. What’s missing? Music! And we’re not talking about those antisocial earbuds that cocooned you through the dark winter. We’re talking about actual speakers that you can take along with you on outings.

Summer’s here, and it’s time to hit the road. Automotive entertainment used to be restricted to radio and whatever you brought onboard in the form of prerecorded music — from 8-tracks to discs and later iPods. But now that smartphones and tablets have made Internet connectivity possible in the car, a whole new world of content has opened up on the road.

We gathered five of the coolest connected- car gadgets and took them out for a shakedown cruise.

The dirty little secret of the iOS aftermarket accessory world (at least where audiophiles are concerned) is that Apple's various bricks and slabs actually sound fairly good out of the box. Output impedance of the headphone jack is comfortably low (around 5 ohm for iPods and iPads most cases, below 1 ohm for the iPhone 4/4s), the onboard DAC isn't a slouch - totally adequate for on-the-go, and for everyday desktop listening, you could do a lot worse.

But that might not be enough for you.

We can bemoan the demise of audio quality all we want, but the truth is that good quality audio has always been at our fingertips. If our digital files have sounded bad, it’s because we (and we’re talking consumers and manufacturers) have been too stingy with our storage capacities. Wanting to cram as much music onto our devices as possible, regardless of how badly the signal had to be degraded to get it all in there, we ended up accepting things like 128 kbps MP3 files as passable. But our beloved iPods and iPhones have had the ability to store lossless and high bit-rate audio from the very beginning, as purists have known all along. You just need a way to get your high-quality files out of those little boxes.

I have seen the future, and it is wireless. Wireless data, wireless music, wireless speakers, wireless keyboards, and now, wireless HDMI hi-def video. (Of course, all these things still need to be plugged into the wall, for AC power. Perhaps, somewhere on the Other Side, Nikola Tesla is still working on that.)

Wireless HDMI gets us that much closer to the Jetsonian ideal of the sheet-of-glass video screen floating unencumbered on a wall – without having to tear down that wall to run wires.

IT’S CLEAR THAT since the dawn of the iPod era, listeners and manufacturers alike have been struggling to figure out what kind of gear makes the most sense for a musical universe dominated by iTunes, and the rise of Apple rivals and music-streaming services has made matters even more confusing.

While the hype at CES this year was all about OLED, 4K, and bigger TVs, a quiet revolution began in the interaction department. LG and Samsung both announced new ways to control TVs using facial and speech recognition, or even just a wave of your hand.

There is a way to make your music sound better. Well, OK, there are LOTS of ways to make your music sound better. If you're looking to improve your digital music, beyond new speakers, amps, and so on is a bit of technological wonder called the DAC, or Digital/Analog Converter. This is what turns your music files into something analog you can actually hear.

Receivers these days tend to have built in DACs, but just because they're there doesn't necessarily mean they're any good. A great sounding DAC can smooth out your digital audio, making it sound more natural and realistic.

Firestone Audio's tiny ILTW packs a lot into a tiny frame, for not a lot of money.

Most headphone amps aren’t made for the way we use headphones. Even many small models are too big to slip comfortably into a pocket. And most require power from an AC wall wart or a USB port. What use is that when you’re stuck in seat 34B of a Boeing 757, miles above Enid, Oklahoma, struggling to get better sound from your smartphone?

Cable cutting. You've probably begun the process already, even if you haven't gone all the way - think about how often you turn to Netflix, or Amazon, or Hulu Plus. And despite the panicked efforts of networks and providers nationwide, when are you watching live TV, exactly, aside from sports?
