The M-75 monoblock amplifiers are one the most musical and fantastic sounding power amps I have ever owned. The meters on the front of the amps show power output. Beautiful design and looks! Rare!

They are designed for those who seek high performance based on high power and fully balanced design, while also concerned with the reliability and ease of maintenance for years to come. The M-75 is designed for full balanced input gaining the ultimate performance supported by transformer assemblies including power, input, output and balance, designed and manufactured by StereoKnight. Two 6922 tubes are used for pre-amplification when the XLR input is selected; a 600 ohm input transformer is designed to split phase for balanced amplification when the RCA input is used.
The M-75 immediately makes clear its wider power bandwidth with more speed, top-end air, improved details and impactful bass. Textures and timbres are finely rendered and silky-smooth, which makes M-75 sound like a single ended class A amplifier. The M-75 is highly engaging, musically rewarding and an unparalleled performer at its price. For the music lover who wants the best attributes of tubes in both style and performance.
