Q The foam surround on my Velodyne f-1200 subwoofer has disintegrated. I wanted to have it repaired with a rubber surround, but the guy at the speaker repair shop advised against that.

Although 3D TV has grabbed its share of headlines over the past year, it appears that many consumers are still wary of the format. To cite one example, more than 70% of respondents in a recent survey sponsored by the cable TV industry said they wouldn’t consider buying a 3D TV in the next 12 months. Wouldn’t consider it! To these folks, plain old 2D movies at home look just fine, thanks. Watching 3D is something that you do while sitting in a squishy movie theater seat holding a bin of buttered popcorn and a 54-ounce Coke.

I've had a DragonFly revolving in and out of my desktop setup ever since I first checked one out for S&V's 2012 Holiday Gift Guide, so I was already very familiar with its capabilities.

When Audioquest released its DragonFly USB Digital-Audio Converter back in 2012, the tiny USB-stick DAC quickly found a niche with audiophiles seeking to improve the sound quality of music played on their laptop computers and listened to via headphones or desktop speakers.
