Dear fellow audiophiles,


I'm thrilled to offer a pair of Atma-Sphere Class D mono blocks, brand new in black finish.


For over five decades, Atma-Sphere has dominated the high-end tube audio gear market. The company's influence is both substantial and indisputable. They are renowned for their superior OTL amplifiers and their stunning MP-1 balanced tube preamplifier. For decades, Atma-Sphere's products have been favorites among audiophiles worldwide.


Recently, Atma-Sphere has once again showcased its innovative capabilities by venturing into Class D amplification. Their latest product, aptly named the "Class D" amplifier, presents a compelling case for making the shift from traditional tube amplifiers.


These little marvels offer the richness, warmth, and musicality of the finest tube amplifiers, combined with the benefits of Class D technology – such as improved efficiency, reduced distortion, and cooler operation. The result is an unparalleled audio experience!


As notes flow through the speakers, you can feel the warmth and depth reminiscent of Atma-Sphere tube amplifiers. The sound is richly detailed, crystal-clear, dynamic, and most importantly, emotionally very captivating.


Atma-Sphere's Class D amplifiers challenge conventional wisdom about what Class D amplifiers can deliver, setting new benchmarks. They stand out, offering a sonic experience truly unlike any other encountered in the realm of Class D amplification.


These amplifiers have received widespread acclaim on audiophile forums, especially for their exceptional tonality, striking transparency, and impressively realistic bass reproduction & dynamics.


Often, the question arises: "Which is the best among Class D amps?" Given the consistent and glowing reviews the Atma-Sphere Class D has garnered, it's difficult not to place them at the pinnacle.


Is it a time to replace your tube amplifier with Atma-Sphere's Class D? I believe their latest innovation makes a persuasive argument.
