Dayton Audio HTA20BT Hybrid Stereo Tube Amplifier with Bluetooth 4.2 USB Aux In Headphone Sub Out
The Dayton Audio HTA20BT hybrid tube amplifier utilizes dual 6F2 vacuum tubes along with an efficient class d amplifier topology 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 MP3, WMA, WAV, and APE. 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.

I was frankly shocked by how good sonically this amp is, warm, sweet sound quality. Ive bought and sold many, many pieces of audio gear over the last 45 years or so, and this amp sounds as good or better than others at 5-10 times the price. I just bought his 200 watt big brother for my MartinLogans. Good job, Dayton.

Purchased in June 2021 so just outside the product support window of 2 years. Fantastic sound using some Paradigm Atom v2 bookshelf speakers in my home office. Now none of the inputs work. Bluetooth still shows connected from my laptop (no sound playing), but cannot find it when trying to pair from other devices via Bluetooth. Also tried some cables into both the Aux1 and Aux2 ports but still no sound. Searched online to find help or at least insight and the manual is no help. Debating whether I try to send back to the manufacturer for repair or look at other options.

Love this unit. The quality of the sound is incredible. Using two Dayton Air bookshelf speakers and a Dayton low-profile sub. All the volume I need for our bedroom. For other applications I might look at the higher-powered version.

This is the “real deal” as another reviewer with a McIntosh system. I bought a $40 bt amp and returned it. This one is a keeper. You won't be disappointed, just amazed.

Tested it out with a couple of knife party tracks and a pair of Pioneer SP-BS21-LR.Can push to very high volumes without significant distortion. You can probably throw a rave with this tiny amp.
