What I currently like, detail, mids and highs.

looking to improve soundstage, have attacking bass. The vocals, seems to be a little to prominent or upfront at this point.

I borrowed some Monster MH 1 speaker cables {true biwire}  and currently hear more detail in the highs. Bottom end did not change much.

Is it in the cables or in my head?
