The manual states a dedicated 20A circuit is recommended for the 755. My HT is in my family room which is on a 15A circuit shared by all the HT equipment as well as room lights. Does anyone have experience they can share when running the 755 in this type of power situation.

I did a search and found the following, which is a partial answer: "Also, something to keep in mind is the difference between max rated load and real-world load. 1800W is the maximum that can be provided by a single 15A residential receptacle circuit, if I remember correctly, so if the 755 ran at a constant 1800W it would require its own dedicated circuit just to keep from tripping the breaker. In reality, the load will be significantly lower than that."
