So I just bought a real nice pair of Kappa 9's. Had Qa's in the old college dorm back in the Stone Age and I guess I never lost my taste for Infinities. Good memories there... I had been using Klipsch LaScalas with full Bob Crites upgrades. They sound great but since we are all crazy in this hobby and continually looking for "that sound" here I go again... Im going from super efficient to something that may require an arc welder as a power source apparently. I have currently been using a Sansui BA/CA 2000 combo with the LaScalas. I have also used an Accuphase E-202 and Luxman R-117 as power sources with the LaScalas. They all sound very good but the Sansui probably sounds the best to me. The rest are on the shelf for now. I also have a NAD 3150 laying around somewhere. I want to power the Kappa 9's properly without breaking the bank right now. I will upgrade later if necessary. I have Denon POA 6600 Monoblocks for the Kappas. Not sure if they can go solo. I was thinking of using these to power the bottom end. I would like to power the top end with the Sansui BA 2000. I would like to use the Sansui CA 2000 as the preamp for all of this. I also have the matching preamp for the Denon Monoblocks as an option. I'm hoping someone can help me so I don't melt anything near and dear to me. Any comments are greatly appreciated. Thanks in advance!
