I have a complete set of the older series from cadence and I've been very happen with them. Powering them is a pioneer Elite, not sure the exact model at the moment, with audioquest speaker wire. I'm a beginner when it comes to audio but I am very happy with Cadence speakers. So much that I'm converting to the 19 series that your looking at. I already have the fronts and am ordering the center channel soon. These speakers take all the power my receiver can dish out and still sound very clear. For the price these speakers can't be beat I can guarantee that, you can get a 5 channel set on Ebay right now for 249 with free shipping. I paid that much for just the fronts a year ago, still cheap in the audiophile world I know. I don't know if this has helped any but I'm a firm believer in Cadence. I have a Cadence amp powering a sub in my vehicle and it's been great for 2 years now also.
