Have you checked out kenwood? Check out all the stats of the 7800, cd5000, cd7000 and compare them to the kenwood excelon x790,x890,x990. I just had the exact same debate. Pioneer vs ecclipse vs kenwood. End result = I ordered kenwood. You gotta be careful with the cd5000 b/c a lot of amps dont accept preout voltages above 4-5 volts. while that has an 8volt. Just some food for thought.
Ive used an eclipse on an amp that has a low imput voltage, had no problems. Im about to try 16V with my BLA //content.invisioncic.com/y282845/emoticons/up2something.gif.dd110ecf3ae4b76050d87598f2f8de7c.gif
