First, be patient. See the head-fi posting guidelines for how long you should wait before bumping a post: http://www.head-fi.org/t/714421/the-dx90-by-ibasso-sound-impressions-and-possible-ways-to-improve-what-you-hear
Next, head-fi is a headphone forum. For speaker setup, you might want consult websites that focus more on that like Audioholics discussion forums, AVS forums, AVforums, etc.
What do you mean by "setup?" Audioholics has quite a few resources on placement. Here are some:
Blu-Ray forums has more (google it).
If you are looking to buy a living room speaker setup, then you would need to provide a lot more information on any website you post to get help:
1) your listening preferences and intended usage: %music/movies/gaming
2) how many channels: 5.1? 2.1?
3) what sources do you plan to use (plug up) with it
4) any size or aesthetic restrictions
5) how big is the room
