Need BAT Help PLEASE VK-6200 vx VK-600 for 2 Chan

My need is for 2-channel only. I just started the purchase of a VK-6200 for 2 channel music only. I put a deposit down and was happy with the amp until my friend ratted me out and told me I should not buy this amp and it is only good for HT and I should just pay more and get the VK-600. The VK-600 is $2300 more and I really don't have the money but I don't want to make a mistake and buy the VK-6200 if it is a mistake and it is really just a HT amp. I read good things about the VK-6200. I have bought a nice used pair of Wilson Sophia 2's. I have a CAT SL-1 Signiture MK3 preamp and a PS Audio Direct Stream DSD DAC and the cables are Carda's Clear. Can you CAT folks please please give me some feedback please. Is the VK-6200 a good amp? Will it drive my Speakers IYO. Is the VK-600 that much better? Please any and all feedback will be deeply appreciated. Thank you very much !!!!
