Pump up the volume and enjoy crystal-clear sound with the AuricSound A7 Vacuum Tube Amp Stereo Hybrid. This powerful device was designed as an amp, but it doubles as a Hi-Fi system. With 50+50 watts to play with, you can raise the roof with your favorite tunes. Furthermore, the A7 has balanced XLR terminals to deliver professional sound quality. You can also use the built-in digital filters to suit every occasion. On the standard filter, you enjoy warm sound with crisp trebles and a deep bass. It has no cooling fan, and the device is very energy-efficient. This is all very impressive given that the A7 measures just 2.67 inches tall. The compact footprint suits even the smallest apartment. With minimal circuit noise and a high linearity headphone port, this amp-stereo is the real deal.
