McCormack DNA-1 vs Odyssey Stratus vs Marsh 400


I am thinking about trying to upgrade my front end amp. I am running 2 of 5 channel from my Rotel 1095 (200WPC) to my Proac Studio 200.

My budget. I am trying to stay below $1K for the amp any a mid-level aftermarket power cord (Am using VH Flavor 4). That said my budget is around $750 -$850.

After reading thru several forums McCormack DNA-1 or DNA-1 deluxe, the Odyssey Stratus Plus or Extreme and the Marsh A400s all appear to be viable options. I need your help. Which of these would you recommend and why? Any other suggestions?

Thanks. Do you know if they will be a step up vs my Rotel 1095 presently being used?

I also have the option of spending the same amount on a dedicated CDP such as a Rega Apollo or an older Arcam or Cary 300. Am presently using a Denon 3910.
