Reviewed: MA2375 Vacuum Tube Integrated Amplifier Receives 6-Star Outstanding Rating
“It delivers more than enough power, sounds crystal clear even when I crank up the volume, and offers an open, detailed and focused presentation. ...Its sound combines warmth with transparency, offering a solid bass foundation, excellent resolution and an expansive soundstage.”
In his review, Lasse Svendsen of Lyd & Bilde explored what makes the MA2375 Vacuum Tube Integrated Amplifier special, calling it a “refined and powerful tube amplifier” and highlighting its unique ability to combine warmth, transparency, authority, and musical engagement into a single component.
A Return to True Tube Amplification
Designed for listeners who value flexibility without compromising analog purity, the MA2375 is our first all-vacuum-tube integrated amplifier in more than a decade, combining six analog inputs, a dedicated tube preamplifier, and tube power amplifier within a single chassis.
Its power section features four KT88 output tubes and four 12AT7 driver tubes, and according to Svendsen, “It delivers more than enough power, sounds crystal clear even when I crank up the volume, and offers an open, detailed and focused presentation.”
Warmth Meets Transparency
Tube amplifiers are often praised for their richness and musicality. What impressed Svendsen was how the MA2375 balances those traditional vacuum tube virtues with exceptional clarity and resolution. He describes the amplifier as combining a warm, rich sound with “a high degree of transparency and detail,” creating a presentation that feels both immersive and highly revealing.
He added, “The MA2375 seems to deliver music with an elegant, almost nonchalant effortlessness. …The way it reproduces vocals, percussion, contrabass and piano draws me closer to the music. Or perhaps it's the music that comes closer to me.”
An Expansive Soundstage
One of his most enthusiastic observations focused on the MA2375's ability to create a remarkably large and dimensional soundstage. When paired with Bowers & Wilkins 805 D5 loudspeakers, the MA2375 produced what the reviewer described as an “unusually grand scale.” Connected to Sonus faber Serafino Homage G2 speakers, the music appeared to extend beyond the physical boundaries of the listening room. “The soundstage genuinely amazed me.”
This ability to create space, depth, and dimensionality is one of the qualities that has long attracted listeners to vacuum tube amplification, and the MA2375 delivers it with confidence.
The Verdict
The review concludes that the MA2375 rewards listeners with a musical presentation that is difficult to resist. “Its sound combines warmth with transparency, offering a solid bass foundation, excellent resolution and an expansive soundstage,” Svendsen said. “For those who value a warm, refined and engaging musical presentation, the MA2375 is hard to resist.”
