Dayton Audio HTA20BT Hybrid Stereo Tube Amplifier with Bluetooth 4.2 USB Aux Inp

Overview
The Dayton Audio HTA20BT hybrid tube amplifier utilizes dual 6F1 vacuum tubes along with the efficient TDA7491HV to provide an unparalleled audio experience. The subtle character and warmth introduced by the tubes create a delightful homage to the classic valve amplifiers of the past.
With a power rating of 12 watts per channel at 4 ohms, and an astonishing THD of <0.1% make the HTA20BT a great solution for near field applications. Bluetooth 4.2 ensures the best possible audio quality and functionality with any wireless device. Dual rear mounted RCA inputs allow for more long-term connection of larger audio devices, while the USB input on the front will read most common audio formats including FLAC, APE, WAV, MP3, and WMA. Easy access onboard controls allow for track selection at your fingertips.
A dedicated switching headphone output allows the HTA20BT to double as a high quality headphone amplifier, while the high quality binding posts ensure a solid connection via either banana plugs or up to 14 AWG speaker wire.
