If you have ever heard anything about the original Onix company, you know what a great amp this is. This particular model was one of the last made in england units before they sold out to a larger company in japan and started producing junk. The sound of the earlier units have been described as sounding very naim/exposure. It is rated at 50 wpc. This unit does not include the optional phono stage. It received its rating due to age, and 2 scuffs/dings that I have included pictures of. If you are in to the 80's/90's british minimalist amplifiers, this is the ticket!
Sorry, just realized that I forgot that this is the OA-30 series 2, not the series 1.
