Receiver Too Weak?

OP-One more thing..(my Columbo...)

I really got as big boost in my HT system when I used the pre-out to a separate 3 way amp (It was an Acurus 200x3) to handle the fronts and center channel.  I mean EVERYTHING changed then and there.  My setup was a Denon x4500h (still in the system handling TV sources) and the Deftechs: 9080x fronts, CS 9040 and SR 9040s for a 7.2 system.  The fronts had 12" woofers but I still used  2  8" subs. 

Just consider what you've been seeing posted so far:  If you want a great HT system you need high sensitivity speakers and a moderate to high-powered amplification from a outboard amp or heavy duty AVR.

Again, good luck!

First, thank you all for the responses and sorry for being slow to respond myself. I think these are the answers to the questions I saw…

1. I don't really listen to a ton of music on the system. I watch tv/movies and play video games. 

2. The sub is a Martin Logan (https://www.martinlogan.com/en/product/dynamo-500)

The floor speakers are bi-amped and the setup for it in the receiver settings is done. Should I undo that? If I understand correctly that would reduce the power which will make them perform worse, but maybe the balance will be better until I can improve my equipment? Or does bi-amping not really work as well as it sounds like it should?

- Remove the "biamp" ....not the right thing to do with a low/bottom budget receiver.

- Read the receiver manual front to back. Learn how to setup and run a calibration correctly...and understand all features.

- Read some of the comments above again if music is a priority. For just TV and games, don’t worry yourself too much..do whatever...
