Purist, Legenburg or K-S?

My new W/P 8's make my Cardas GR sound somewhat reticent.
I would like something a bit more engaging.
I lean toward uniform cabling througout the system.
I have had favorable but limited experiences with each of these contenders and would appreciate any other considered opinions.
I will pony up the necessary spark, BUT:
I am unwilling to become a dealer to support my habit.
