Then again, the track I was listening to was encoded in FLAC with 24-bit resolution and a 48kHz sampling rate. Few wireless technologies can deliver that kind of throughput. Given that the E5 can almost as easily serve as a wired host to my phone, I think I'd probably just plug a cable in anyway. If you're a Bluetooth maven, you'll want to know that the E5 can connect two Bluetooth sources at once and toggle between them.
A worthy purchase?
Audio snobs will look down their noses the Sound Blaster E5, but I see--and hear--a ton of value in this little box. I'll probably never use some of its features--the integrated mics, the CrystalVoice effects, and Scout Mode among them--but the E5's price-to-performance ratio is off the hook even if you only ever use it as a USB DAC and headphone amp.
