Thanks for the responses everyone, some very interesting insights.
From the AudioQuest site, here's the blurb:
"Launched in 2012, press and public alike have enthusiastically embraced AudioQuest’s multi-award-winning DragonFly USB digital-to-analog converter/preamp/headphone amp as the rare audio product that bridges the gap between die-hard audiophiles and mainstream music lovers.DragonFly plugs into a computer’s USB port to bypass the computer’s compromised audio circuitry and deliver cleaner, clearer, more naturally beautiful sound to headphones, powered speakers, and complete audio systems. Small, affordable, easy to use, and remarkably effective, DragonFly was named Stereophile’s 2012 “Computer Audio Component of the Year” and 2012 “Budget Component of the Year;” Tone Audio’s 2012 “Digital Product of the Year;” Computer Audiophile’s 2012 “Computer Audiophile Product of the Year;” AudioStream’s “Greatest Bits;” and What Hi-Fi?’s 2014 “Product of the Year.” @ Kev999 . . . you are correct, I was mistaken, it doesn't plug into the headphone jack, it's a USB device, so there must be drivers to install . . . if it truly bypasses any computer's audio circuitry, isn't it just another audio interface ? . . . except when you're actually recording, it must still be routed through the computer's main audio interface.
@ filtersweep, synkrotron, and AT . . . I definitely hear a difference plugging the headphones between my USB Audio device, as opposed to directly into the laptop headphone jack . . . it wasn't a cheap laptop, it cost around $2500 CDN, so I was expecting the audio components to be half decent, but it seems I have to customize it further for serious audio, since this laptop was not originally "designed" for audio work.
@ Cactus Music . . . guess I'll just have to take my laptop and some of my mixes to the retailer, and actually hear the difference. I'm curious to see how the sound is altered by this device, and whether it's an accurate reference for monitoring the projects.
The headphones I use are KRK KNS-8400 . . . so not top of the line, but still $300 decent.
Of course, I use this laptop for mobile recording and composing . . . I still only trust my main studio desktop system for final mixes.
