I just a/b'd the two last night. The Meridian was much warmer with greater depth, more forward, and didn't have the punch you in the chest bass that I find annoying. The Arcam may have had a little more detail, but was very flat in space, had that hard bass I mentioned above, and lacked the presents of the Meridian. The Arcam was ...thin. I think I am going with the Meridian.
