Hi, I currently have a Marantz CD6004 CD player, however I am looking to upgrade it to a Rega Saturn-R in next few weeks. Can I expect a significant difference in sound quality for the money? The rest of my system consists of a Rega Brio-R and AE 301 speakers, I know they're not very ideal for a high-end CD player but I will also be changing them sometime over the next couple of months.
