very true, it gets overwhelming, but its fun

@asmithkash Well, it goes back to a question I have regarding the power you think you need for the speakers. I have not looked them up so I don't know impedance specs. 

I am sure some would disagree but I consider impedance across frequency range more important than sensitivity when it comes to the power needed. Sensitivity relates more to how a speaker plays into the room. Impedance relates to how the amplifier interacts with the speaker. The size of your room helps. It is similar to my own.

I should add that I am not familiar with the sound of your speakers, just that you like the way they sound with your AVR. I am positive you are going to be please with the road you are about to travel. A high quality 2 channel integrated amplifier will take you much of the way.

I prefer some warmth, with a non aggressive or tipped up  treble, and articulate midrange in my speaker. 

Are your 804s the one with a pair of 6.5" woofers?  

I would think that you may not need the subwoofers you were thinking about in your original post. A small room supports base energy. For music it can get to be too much. 

The speakers are great.

Get the Krell.

Enjoy.
