Interconnect with great dynamics and bass slam ,


I recently purchased some Cardas Golden cross sepaker cables. They replaced my Dh Lab Q10s. I replaced the Q10s because i was getting some upper mid freq brightness.
I have Golden Cross interconnects from preamp to amp and from cd player to pre amp. The sound is very smooth and detailed .The bass and mid bass is not as authorative or as tight. The highs are better - more detailed and smooth.
The problem is the sound is almost too smooth the bass is kind of rounded off now .The sound is less dynamic.
My Question is.
Is there an interconnect that could give me back that great bass and dynamics of that i had with the Q10s, without the harshness i was getting. I think i would like to keep the Golden Cross speaker cables and try changing the ICs. Any thoughts would be greatly appreciated.

My last question here was asking which interconnect should i use for the pre-amp to amp on the bass cahhels . I am bi-amping . This is for the pre-amp to amp ( the bass channels to the speaker) .they are crossed over @ 150 hz . So the signal from the amp to the speaker will only be 150 hz and below .
What i am using now is Golden Cross ICs. That seems a waste for 150hz and below .i was asking for some suggested ICs That are good for Bass (Tight and defined is what i am looking for ). The speaker cables for the bass are DH Labs Q10s put together with Synergistic Research #2s. Both are used together , right now
