Manley stingray or Cary sli 80 sig

I have a nice tax refund on the way and want to replace my seperates with a nice integrated tube amp. I currently have a classe dr6 preamp and a dynaco st70 powering quad 11L speakers. The sound is nice and warm( I really like the tube sound) and am trying to decide if I should take the plunge to a Manley or Cary or upgrade to a fuller sounding pair of speakers.

My listening room is 10x10 and carpeted.

Has anyone owned both of these integrated amps and which one do you prefer and why? Any suggestions appreciated.
