I'm using onkyo 905 very powerfull & full DSP support. Its hot (not so) but all class A amp is also hot (my tube amp also very hot).

If I have the budget like yours I will audition Mirage complete set (very small but special)or MS Mezzo complete AV set or Paradigm Reference & Signature or Klipsh RF-82 or MA Silver & Bronze set and last KEF Reference. Wow! They all my dream HT set matching with Velodyne or Paradigm subwoofer. All set also excellent with music & may be not touch RM18k budget.

Cheapest from all may be MS Mezzo (Mezzo 2 + 5 + 8 + sub). We could audition all this in Malaysia(Amcorp). Sorry if 'syok sendiri'.
