CelestialSounds is a high-end dealership in Stellenbosch, South-Africa. Our website can be found here: 

  • These Audio Research Reference 750 mono block amplifier pair is the export edition meaning their are wired for 230V 50hz ac operation. We do not perform voltage conversions, but we are pretty sure it is entirely possible with the guidance of a professional ARC technician.    

  • The pair of amplifiers listed here come from the original owner/buyer for whom we've installed the pair about four years ago. We removed them again at the beginning of this year when our client upgraded to Gryphon Mephisto amplifers.

  • These REF750's are the KT120 version prior to the current 'SE' with KT150's. Tube hours on the amplifiers differ with about 240 hours and we can only account this to a possible accidental reset of one unit at some time early early on. The reset button on the REF750 is mounted on the exterior just below the hour meter. On other ARC amps the reset buttons are mounted inside the chassis. Tube hours read 1070 hours and 830. 

  • The KT120's in these amplifiers can be replaced with KT150's without modification.   

  • These amplifiers are otherwise spotless or 'as new' with zero blemishes of any kind. The only reason we give it 8/10 is because of the difference in tube hours. As a dealer we are inclined to lean toward underrating rather than overrating our items. 

  • These Reference 750 mono blocks were used to drive the ribbon tweeters of an active crossover pair of Dali Megaline III loudspeakers. The bass (heavy lifting) was performed by a Jeff Rowland model 825. 

  • The room was air-conditioned and smoke free so the amplifiers had minimal dust contamination. Before we assembled them in my dedicated listening room we blew the little dust there was out with compressed air.   

  • For shipping, the amplifiers will be packed in their factory cartons with factory packing material. There are four boxes in total. Each amplifier has a separate box for the valves, manual and power cord to go into.  

  • For international shipping it is best you contact me (Leander van Rooyen) on +2782 088 6688 to discuss options and payment. Shipping is for buyer's own account and risk. Total weight for the shipped pair is 395 lbs or 180Kg.   

  • For payment we accept all major credit cards. Wire Transfer and PayPal is acceptable. For PayPal please add 3,5%.
