Cary Amp and B W Nautilus 805's

Does anyone have any experience with Tube amps and B&W speakers? Right now I have a 100w Mcintosh 7001 amp running B&W 602 II’s. I hope to soon upgrade to the Nautilus 805’s. I’m VERY interested in the Carry SIGNITURE SLA 70B amp. I have seen these sold for a reasonable used price but haven’t found any resources anywhere to learn about them. Are they SET? What are the pro’s/con’s of Push pull amps? I really want to get into Tube Amps but….. Want to spend $1000 or under and want the ability to CRANK up some ‘well produced’ classic rock every now and again!
