I would pick up a used Bel Canto DAC2 with a used Acoustic Zen Silver Bytes digital cable to use with the NAD player, assuming it has coaxial output.
This will be a pretty big step up from where you are now or from where you will be with the Music Hall units.
And I would pick up a used preamp as well. Adcom GFP-750 comes to mind and should match pretty good with your Adcom amp. On the upper end, Pass X2.5 preamp would be nice.
This will summ up to under $3k, will sound better than what you're auditioning now and you will have some money left to buy more music.
The components you are currently considering will most likely satisfy you for a year the most and then you'll be on the merry-go-around.
