Currently I own a Kenwood-910 Music Keg and my H/U is A Kenwood Excelon x-879. I want to replace the keg with something better but I'm confused with so many choices. I can get my hands on an Empeg MkII. I have also been looking at the following units as well the Alpine HDA 5460 and the Dension DMP3 and the Dension 100ix. Any insight that someone can provide is appreciated.
