JOB, BelCanto, Perpetual, MilleniumDACs?

Greetings. My evolving ref system (ParsifalEncores/AlephP+2s/RedDawn) needs a new digital front end. I've read about the DACs listed above, and hope to hear commentary that might save me enormous time comparing them. This system is WAY too revealing of my old Rotel CDP's inadequacies (HF roughness, especially), but a quick fix with an ARCAM 9 proved unsuccessful: it's too rhythmically handicapped! Is the 'Canto the easy solution to achieve high resolution AND rhythmic prowess? Thanks. Ernie (Whatjd: lost the thread with your comments--please repeat, if you would be so kind.)
