The Onkyo MD-133 has the unusual honour of being the first Hi-MD component ever released. Part of Onkyo’s INTEC 275 range, it combines gracefully with Onkyo’s other INTEC 275 components to form a mini component Hi-Fi system, integration with RI serial interface. Manufactured since 2005 to 2011 at least.
