M600 (600:600)

M600 (600 : 600 Ω)
The Kraftwerk M600 is a mastering-grade line output transformer designed as a direct evolution of the Marinair lineage. With a true 600:600 Ω impedance ratio and a high-mass EI57 CRGO M6 core, it delivers powerful low-frequency extension, reduced harmonic distortion, and a naturally smooth top end.
Its oversized core gives the M600 exceptional headroom and weight, while maintaining a musical, vintage-inspired character—ideal for summing, mastering, and final output stages.
