I have the same RM9 MKI that I bought from Johnny Rutan at the Audio Connection in 1987. I have had it worked on 2 times in 21 years. It is currently tubed out with Genelex Gold Lion re-issues and 1960s Heerlan Plant Amperex E88CC. Make no mistakes about the tubes I tried them all and there is no comparison with the KT88s. I am currently Driving a pair of Merlin MXE's and it sounds to my ear beautiful, super balanced and as pleasant as it gets to listen to. I have heard systems that had $40,000, wrapped up in them and-well sorry I can't help you there. The RM9 is a timeless amp and I will never sell mine. I have an ARS Sonum integrated on the way we'll see how they compare. I say get one and save yourself $10,000.00
