AudioQuest Niagara 1000 and Bose Lifestyle?

not worth it, and it should have some value on ebay

Not worth getting an Audioquest Niagara 1000 or any power line conditioners / distributors designed and built for hifi or high end audio or high end HT if it's for Bose lifestyle. Just stick with what you currently have. 

Not worth getting Audioquest or any other expensive power cables If it's for Bose. And besides Bose Lifestyle comes with its own proprietary AV receiver and not sure if the power cable is detachable or not. I doubt it is detachable. 

So, the Niagara 1000 and power cable upgrades are not worth it for Bose and won't do any good and most likely you won't be able to tell the difference sonically unless if you have real hifi and revealing setup/system.

Yes, I have AQ Niagara 7000 on my main system, and I definitely noticed a significant difference with that and upgraded AQ power cords. 

I’m thinking I may put the Bose Lifestyle on eBay and see what comes of it. Would have been better off with 2 pair of B&W 685 S2 and a HTM 62 S2 and a Pioneer or Marantz receiver.

Yes, Niagara 7000 or 1000 would make significant difference in high end hifi setup/system but not on Bose. What is your main system? 

Yes, B&W 685 S2 surround sound speaker system with either Marantz or Pioneer Elite receiver would definitely a step up from the Bose Lifestyle audio performance wise. Now with that setup you can get the AQ Niagara 1000 and upgraded power cords. 

The term "polishing a turd" seems particularly relevant here. Sell that crap for anything you can get for it and take it as penance for making that terrible decision. Look at this as a rebirth and console yourself with the realization that nothing but much better things lie ahead.
