Tom Lyle has posted a review of the Audioengine HD6 Premium powered speaker system ($749/pair) at Enjoy the Music. His conclusions:
“I can’t recommend the Audioengine HD6 highly enough. This amplified speaker is perfect for music lovers and audiophiles who need a small self-powered speaker that works in many applications – from replacing one’s crappy computer speakers, or to enjoy in a second system in one’s office or other room where a larger speaker will not fit – I can’t think of any other self-powered speaker that can provide much more than simply a “decent” sound plus negate the need for an amplifier, preamplifier, and DAC.”
