Replacing Sophia Baby with Rogue Cronus worth it?

I'm new to tubes. Always swore I wouldn't go there. But I've had my Sophia for a month and I'm already looking at upgrading (?) to a Rogue Cronus. I use the current amp with only one source, a Pioneer universal disc player and with my 80's ADS L780/2's (89 db). I'm blown away by the imaging, especially the depth and the truth of timbre. Is it just "the wanties" or would the Rogue justify paying another $1,500? I'll read and consider carefully any responses. Many thanks,
