come on guys I need help

This is such a personal and system dependent suggestion, but I have been very happy with my Signal Cable Silver Resolution cables for a combination of smooth sound and excellent detail through the complete audio range.

the discovery cables are fine, as are the speakers and pre......not sure about the amp(not familiar with it). sounds like moving the speakers around might help....couldn't hurt to try.....the front end may be a problem, but this sounds like a room thing.

Jaybo is likely giving good advice. Nothing in your system is substandard at all, it is unlikely that genuine component defficiencies are the cause of any muddiness or lack of detail. If you go to www.acousticsciences.com (makers of "Tube Traps," their website has a mp3 audiofile to download called the m.a.t.t. test. You can just Google "ASC matt test" and you'll go right to it. If you have headphones, earbuds, etc. you can hear the tone sequence as you should, then play the tone sequence through your system and you'll get a sense of the degree to which room acoustics are contributing the impression of muddiness and lack of detail. This test is aslo on Stereophiles' second test cd they issued.
