Odyssey "Khartago" Stereo Extreme" amp compared to Schitt's "Vidar" amp

I am downgrading my amp to a smaller size and considering either Odyssey Khartago Stereo Extreme  or the Schitt Audio "Vidar"  Therefore, I need some feedback about which amp might sound better and more compatible with a Conrad Johnson PV-14L SE pre-amp. Also, which one would be more compatible with a variety of speakers

My current speakers are Golden Ear Technology model 7's which might  possibly be replaced by Magneplanar .7 speakers, or something better than the GET 7's.

Thank you,

S.J.
