Classic tube warmth with contemporary design

At the heart of this stereo is a hybrid tube amplifier with vintage flair and modern connectivity. By combining a tube preamp with a contemporary solid-state amplifier, the HTA20BT provide the warm and fuzzy sound characteristics associated with vintage tube amplifiers while generating clean and efficient power common in modern amplifiers. Simply stated, this will sound amazing while remaining as energy-efficient as possible. Eliminate the hassle of long cables and go completely wireless with the built-in Bluetooth streaming, or connect any analog device to the two RCA inputs for easy integration into any desktop system.

Extraordinary Dayton Audio bookshelf speakers included

Enhance your listening experience with these small yet impressive bookshelf speakers. The unique geometric design and black vinyl finish give the MK402X bookshelf speakers a clean and dignified look. More important than how these speakers look is how they sound, and they sound fantastic. A built-in crossover ensures that the 4" high excursion woofer and 3/4" silk dome tweeter work in unison to provide well-balanced sound with great bass response, a smooth mid-range, and high frequencies that are sharp but not shrill.
