Pass Labs X350 vs Mac 402 Vs Theta Enterprise vs.,

Parasound Jc-1. I am looking into these 4 amps to upgrade from my Theta Dreadnaught 11 7.1 setup. I would like a true stereo setup. I currently using a Casa nova pre. I am looking to drive my tyler acoustics Linbrook 1 peice speakers. All these amps around the same price . I listen to mostly rock to classic rock would like some slam with tube like sound. I have read all the reviews. Please any help to out there I would appreciate . Thanks joe
