Belles Aria upgrade over VT01, sa100, sa030?

Hello

I´m a big fan of Belles after have been playing with a vt01 ans sa030 version 1 over tons of other equipment much more pricier.

I´m driving a pair of Peak Consult Jeanne D´arc with no problem. Soon Ill upgrade to another set Peak Consult and want an ekstra power amplifier.

I wrote to Dave - because my first thought was to buy a sa100 and use that on the "low" input in the speakers.
Thats an option and they will fit together
 
But then I wondered.

Is the Belles Aria line out performing the older vt01/sa100/sa030? 

I dont know if I should stick to the "older" set or go for the newer Aria line with 2 power amplifiers.

What do you guys think in here?
