Hello everyone new to all of this and I am looking for some help here goes.
I have
2-rti 5s front
1 -cs 20 center
2-lsi7 middle
2 vintage m&k sb2 rears
1-dsw pro 600
The problem I have is the center and fronts are 8 ohms the middle and rears are 4 ohms. I do not have an avr yet but looking at the Denon avr3808ci. After doing some research I found out the 3808ci will not work because of the 4 ohm load. So the question I have is could I use the 3808ci as a pre amp or could I use it just to drive the 2 front and center speaker. Also if I could what would I need as an amp for the other 4 speakers. Or should I trash that idea and get something different. Any help on a setup with what I have as far as speakers go would greatly help thanks for all your input.
