I have B&K 7270 200 X 7 at 8 ohms and 375 X 7 at 4 ohms power amp and Paradigm Signature S-4 Speakers. The preamps min volume is -96 db. I dont hear any sound from the speakers until -60 db.
My max volume is at -15 db. I am not sure If I am driving my speakers/AMP hard. at -15 db I dont see any clipping. As I dont have a sub right now I feel base is not powerful enough. I am soon going to get a sub anyway.


One more thing is B&K amp is getting hot. But I see no clipping until this point. Does the life of the amp has any impact because it is getting hot.

My question for you guys is how do I determine when I am running the system too hard.

Another thing I am planning to do in next few days is to bi amp my speakers. I am only using three channels right now. L,R and center out of 7 channels available in the amp.
I intend to use two more to biamp my L R speakers.

I know power usage in the amp will increase but does the amp sustain the load. Have anybody done this before let me know.

Thanks
