It depends on the use - the original post indicated "I want to mount in the bedroom to improve the audio when watching tv. I may also use it for some background music, but not looking to bring the house down. " For that type of use, I was just recommending things that likely are reasonable and likely won't be a problem. If someone indicated they might want to use it for more taxing listening, I probably wouldn't have put it forth. For TV listening and background music, I am not sure most things will have a huge problem. I have an old $80 105WPC Sherwood receiver on an old back-up computer and it had no trouble when I had it hooked up to 4 ohm speakers at one point for light background use. I had it in the bedroom (which is an average sized room) for a short time powering Thiel SCS2s. I would not use it for other than what I did though.
