I am not familiar with MF E60 CDP but if it has a digital out the biggest single improvement you can make is upgrading
DAC with Bel Canto DAC 1.1, this does more to remove digital
hardness/leaness than anything else you will do. Slow roll-off filtering is the key, while giving increased detail at the same time. This will make bigger improvement than Sony 777ES on regular CD playback.
By all means replace DH Labs with Analysis Plus, superior in all respects and much fuller more natural sound. Cardas GC is top shelf but is very expensive for what you get. Also keep the Sim Moon I-5 for now and concentrate on your DAC, that is by far your weakest link currently.
