Hey Guys this is my first post and I need some advice from an expert I am currently looking at a Harman Kardon ( AVR 745) and Infinity Cascade model 3 speakers along with a Cascade model 12 sub. Will these components work well together and what trouble will I have setting this up. I can get special pricing on Infinity JBL and HK products so I would prefer to use those products. Thanks !!!!!!!
