Torus RM-15 or Bryston Bit-15 owners. Do you plug in your amp to them?

I have a nice Furman 15 PFI unit but I don't plug my amp into it.  Instead, I plug the amp into the wall.  Sounds much better.
I'm thinking of moving to the 15 amp Torus or Bryston models. What I am interested in is the amplifier headroom they provide which could allow me to move up from my Bryston 4bst to a Bryston 4bsst2.  I'm thinking the Torus/Bryston could help deal with any additional power load/spike that a slightly bigger amp might draw.  
My main listening level is around 80 db with peaks at about 86/87 db.  The bigger amp might cause me to increase my listening level 2-3 db, which could become significant.
I should point out that my listening room (basement) Is purposely not hooked up to heat or any duct work.  It is very quiet in there.  Instead, in winter, when I go downstairs to turn the equipment on and let it play for an hour or two before I start listening, During the warm-up I also run a 1500 watt space heater which I turn off once I start listening.  I warm up the system at almost the same volume as when I'm listening.  The heater is on the same circuit as my system.
So, far I have never noticed a problem with current draw, but I think I would go with the extra protection of the Torus/Bryston Power Conditioner  IF  I would plug my amp into the conditioner, rather than the wall.  This is totally a sound quality issue.  
So, if you have one of these models, (I'm more interested in responces from people with the 15 amp models), do you plug your amp into the conditioer, or does plugging into the wall sound so much better that you skip the conditioner.

Thanks,
Tim
