Jaymark, I have had the X5's for a year and a half now and they are truly amazing sounding now that I've had over 500 hours on them.
You mention you had the upgraded crossover in your speakers, are you saying that you ordered them with the VH odam capacitors? Mine came with the Clarity Cap capacitor so it seems Clayton now uses the VH Odam capacitor or offers it as an upgrade. I believe he did as well when I had ordered but I don't know much about capacitors and if the difference between them is significant or not. I know I can easily bypass the Clarity cap and insert a different capacitor outboard if I want to experiment, who knows maybe I'll try that but the speakers sound so good right now I don't know if I want to even experiment. I'm running low powered tubes with them.
