Sometime can depend on where you got that 125w from before, receiver?
The 1050 (at 60/65w?) is know for many owners posting it ran their speakers more effortlessly than prior models owned rated at higher watts. Outlaw power seems to DO what its says.
Depends on several factors, I can pretty much guarantee either sound fine with the 950.
But the other things can get cha! What’s your speaker sensitivity? How big a room might you upgrade to, what dB do you normally listen at?
If I was stuck (Depending on your speaker sensitivity) I’d start by answering the question, which would I likely do first? Enlarge the HT space, or add two speakers? And if I decided its just a comfort zone for me to go with the 200w will I be bothered by space considerations adding monoblocks or 2-ch amp later, if I expand to 7.1?
