I dare to say that my rig is performing excellently now.
It could hardly be better.
The limiting factor is only cables (I think).
At the construction of my house I had constructed a 7 x 7 m. square room with hollow floor, for best accustics.

The chain that does now generate to very best sound currently is:
2 x Isotek Genesis One, 4 x Furutech DPS 4.1
Aurender N10
Totaldac D1-direct
silverplated RCA interlink
2 x Totaldac D1-driver
silverplated XLR interlink
2 x Classé CA-M 600
Bowers&Wilkings 802d.
