Ortofon: 'Accuracy in Sound'
 
Ortofon is the world’s oldest and most experienced manufacturer of hi-fi pick-up cartridges. From humble beginnings in 1918, Ortofon is now a prolific winner of various international awards, and consistently well reviewed by the international press with every new product. Their core principles of responsibly sourced high-end materials, meticulous design and production processes, pristine working conditions and superlative attention to detail are evident in every single product they make.
 
From the introductory moving magnet OM and 2M models, through the Vivo, Rondo and Cadenza Moving Coil series, all the way up to the high-end MC Windfeld, Xpression and brand new MC Anna cartridges, Ortofon are devoted to offering true ‘accuracy in sound’. They also commit to supporting long-time customers by continuing to run replacement styli many years after an original cartridge has been discontinued, and for Moving Coil customers they also run an attractive Exchange Program .
 
Nothing demonstrates Ortofon's long-standing resilience more than its commitment to the refinement of analogue sound quality and its continued development of new cartridge models. Since 1948 Ortofon have introduced about 100 different moving coil models, with their latest being the Quintet Series.
Ortofon believe the cartridges in this new series are more than worthy successors to the long line of models that have made Ortofon the global leader in the manufacturing and supplying of phono cartridges.
