Technology hasn’t made everything better. Breasts? Yes, OK, fine, breasts have gotten better. But audio quality has been going the quick & cheap route since the compressed sound of the MP3 came into fashion. The BlueTube Audio Tube Amplifier ($550) looks to reverse that trend with a finely crafted, hand-built tube amplifier that fills any room with rich sound and classic aesthetics. The 3/4″ thick walnut and cherry enclosures are hand rubbed with linseed oil, then waxed. Yeah, baby. Plus the tubes themselves produce a warm glow that surpasses the glow of even the happiest pregnant woman.
