I'm going to buy the Klipsch RF62 Mk2 front and a central Rc62Mk2, but i've a doubt about about the av receiver to abbine. I've read that many people tells it's not good to use as av receiver a Yamaha Rx A1000 or 2000 because the sound will be too open... is this true ? Someone use this configuration ? Any other Av Receiver to suggest ? How the Onkyo 808?
