I have a level 1 mod from Walter and I am thrilled with the performance. The biggest improvement I noticed was in the mid bass and lower end extension. The sound is warm, yet detailed. The Jolida has a very full range sound with frequency extensions on both ends. This is the closest to analog sound that I have heard from a CD player. To get a more analog sound you will have to get a turntable. I cannot comment on the Arcam, but they seem to make quality components.
