I have no hands-on experience with the X590 but the one from a few years previous, the KDC-X569, I do have experience with.
The few shortcomings with that particular eXcelon deck were corrected/eliminated in later models so for entry-level eXcelon I would say it's likely a solid investment. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
