The Dayton Audio HTA20BT (and its refreshed counterpart, the HTA20) is a compact, entry-level hybrid tube desktop amplifier. It is designed to combine the smooth, "warm" sonic character of traditional vacuum tubes with the power efficiency and modern digital features of a solid-state amplifier.
Core Characteristics
-
Hybrid Design: It utilizes dual vacuum tubes (6F1/6F2) in the preamplifier section to add harmonic warmth, paired with an efficient Class AB/solid-state output stage.
-
Power Output: Delivers around 12–15 W RMS per channel into 4 ohms. This makes it best suited for efficient bookshelf speakers in near-field listening environments (like on a desk or small office shelf).
Connectivity Options:
-
Wireless: Bluetooth streaming for smartphones and tablets.
- Analog: Dual rear-mounted RCA stereo inputs.
- Digital/Direct Media: USB port for directly reading flash drives with digital audio files (FLAC, WAV, MP3, WMA).
Outputs: Features standard speaker binding posts, a dedicated 3.5mm headphone jack on the front panel, and a pre-amp subwoofer output to easily add an active powered subwoofer.
