I would vote for HiDiamond D8 that I currently test in my main system, almost everything one needs and are very musical.
A big improvement (and I would start there first) would be to upgrade the Vishnu PC, even in the NordOst line they are underperformers. If you like the NordOst house sound, go for Brahma or Valhalla (2); better still, upgrade to HiDiamond P3 or P4, IME, some of the best value / money in PCs.
