Hey Guys, I'm fairly new to the Audiophile scene and need some help. I have a pair of Ascent i's with a Theater i and two Fresco's for my rear surrounds. My current electronics are Sunfire TGIV and Sunfire Cinema Grand Sig (400wx7ch). I am wanting to upgrade my electronics but I really don't know where to start. Should I keep what I have and just change my Ascent power? Should I be using the balanced inputs or unbalanced? Give me some ideas. This is a HT setup that I listen to a lot of music with.
