From my experiences, if you push/tighten it really tight, it will kill the soundstage and overdamp the sound. Most people tighten it till no tomorrow. You will lose detail and it will kill the soundstage. Try very lightly tightening it. You might prefer it that way.
There are many good atermarket clamps available which will really improve the sound.
