Thanks, Oregon, for sharing your initial impressions. I have been sitting on the fence waiting for more information about the ART 9 (and saving some scratch) before taking the plunge. My OC9MLII/JMW9/Scout has been a very rewarding combination and I have been trying to find a cartridge similar, but more refined, than the OC9MLII that I can afford--unfortunately, to no avail. The ART 9 sounds like it may be the ticket. Please, as you listen more and share your views following break in, provide us with some sense of how the ART 9 exceeds the performance of the OC9MLII--you are probably one of the few people out there that has taken an upgrade path that would be the same as my own. Best to you and enjoy the ride.
