When I read your original post, my initial reaction was to recommend an amp upgrade over the cd upgrade.
When I had a HT rig with Aerial 7b's, cc3 & their surrounds, I paired with a Sunfire 5 channel amp. Great value, smooth balance and incredible power reserves. You can probably get one used for a low price, and readdress the cd issue afterwards. You won't lose any money trying it. People have widely varying opinions about Bob Carver, but his Sunfire gear is great for HT applications, and would probably be a nice fit for you here. Cheers,
Spencer
