Music Hall CD-25.5 vs CD-25 w/mods??

I was going to pick up a NAD C542 but now thinking of going for a Music Hall CD-25. I can get a C-25 w/level 3 mods for $200 more then the NAD but now found I can buy the newest Music Hall MMF CD-25.5 for $540.00 brand new(which is $60 less then the 25 w/mods). My question is: did they improve the 25.5 to the point where it would be up there with a MMF CD-25 with mods?? Unfortunately I can't go much higher $$ wise, $400 was my limit but might as you can see I'm pushing it a bit. Also thinking it maybe overkill considering my system. Any thoughts or suggestions would be greatly appreciated..
My modest system:
NAD T752
Paradigm Studio 20v3
Technics SL-Q2 Phono
AudioSource Sub(next on my list for replacing)
Yamaha CDX-710 CD-Player(15 Yrs old,getting replaced now)
