enigma upgrade for kharma

How big an improvement does this upgrade give and can it be done to my midi grands? Also how much does it cost?- thanks
It is a really nice improvement. Especially when it comes to the vividness and bass resolution. Where are you located? The cost is 4k.
Second JTinn's comment - particularly for vividness. A really clear improvement on the 3.2 crm, so probably even more obvious on the midis...

my mistake they are the grand ceramiques- what cables do you use- I have the sonic frontier power 3 se that has been upgraded by chris johnson-thanks-k
