I need some help deciding whether to get a pre amp or a receiver. My setup will be a 2.0 system for listening to music and watching T.V. I already have a dedicated H.T for movies. My speakers are in the process of being made. They are Salk veracity S.T's in Mexican Zircote. I've already bought a XPA-2 gen 2 to power the ST's. I'm not sure if I should get a pre amp or just a decent receiver. I'm looking to spend around or less than $1300. I've never had a pre amp before so not sure of the adv/dis. I need some expert help and options please.
