received item from seller. Honestly, after hooking up, WOW. Can really hear the difference. Last time i only use a filter, but this isnt joking. The bass from subs are tighter, and the trebles and vocal and details are clearer.

Might be placebo effect, but i dont think so, becos the changes is significant. Nice stuff, next time maybe will upgrade to Bada power plant and switch my 2.2 for desktop
