Manley stingray or Cary sli 80 sig

If you like the warmer sound you might prefer the Cary. My Manley Stingray is a lively sound, but there is more than one version. The later version has a lower power rating due to different output transformers and I have a feeling it is a mellower sound. You may want to check that out.
I don't know what speakers you would get for your 10X10 room.

I don't think you can go wrong with either. Flip a coin, 2 excellent choices.

Not to throw the post off topic but, have you considered the Rogue Audio Cronus Magnum or Tempest Magnum? I own the Tempest and have heard the Cronus numerous times.Both are very musical amps.I use Tyler Acoustic 7U's with my Tempest and together they produce very "lifelike" sound.Either of these amps or the ones you mentioned in the OP,paired up with some really good monitors,would be great choice.Good luck.

I owned both, loved them both. But since I gotta choose: Cary SLI-80.

I own the Rogue Cronus Magnum. It's got some nuts. I'm not a huge fan of how the Stingray looks. It's probably because I've seen pictures of EveAnna Manley who reminds me of my buddy Billy's lesbian sister Renie. I can't imagine turning Renie on when I want to hear some music so I went with the Rogue. I've never been happier and the Rogue is actually a heavier unit. That being said, I'm not into fat chicks. I would love to hear the Cary, although it costs an additional grand. I've never read any reviews that led me to believe that the Cary sounds any better than the Rogue. I'm sure the Stingray sounds great too, if you don't have an aversion to Manley women.
