At home, I currently have a decent setup with some M-Audio AV-40's (LONG internal debate between these and the A2's, but I finally settled for the cheaper solution). I've got them hooked in through a NuForce Icon uDAC-2, which seems a pretty good combination to my aging ears. At work, well, the junk speakers in my monitor. Yeah, I REALLY need speakers in my office since I'm here so much, so I'd truck the AV-40's down here and enjoy the A5+ magic at home. And with the money I saved NOT having to buy new speakers, I'd be able to get a DAC for the office, too.
Hope life at HTC is treating you well! Really hoping to see a Titan on Verizon, so if you have a pipeline to the engineering and marketing departments, let them know!!
