New preamp question

Good afternoon,

I'm looking to replace an Aragon 28k mk2 preamp with either an BAT VK23se or a Halo JC2BP.  Any comparisons that you have had directly with both units would be really appreciated.  Price points are very similar.  This will be connected to an Aragon 8008 mk2 amp and larger Dynaudio speakers.  Cables are WW Eclipse 8.

Thank you in advance.     
The Aragon 28k mk2 is quite nice.....

Especially when paired with other Aragon components.
