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.

I tried the solo crystal ovals . There are very revealing . I did not like their forward presentation though

What is Acoustic Zen Absolute copper ?
I see that maybe they introed it at CES 2013 , but it doesn't show that it is available on their website yet ?
Where would you get this from ?
Contact AZ for disposition but I can tell you that they are phenominal and the best cable I have ever heard. Many sources but here's one:

A couple years ago, I sent a couple powercords back to Robert Lee to be reterminated and he mentioned working on a new cable that would eliminate skin effect and sound really smooth. Are the absolute copper cables those? Maybe. I love their products and look forward to hearing these.
@ grey9hound,, stick to the Taras! you have a good plan to follow with the taras,, as you can see, nobody that bought them had no regrets! cheers!
I wouldn't mine trying those AZ Absolute copper , But they are out of my price range.!
I'll keep my eyes open for the Air 1 or the One to try first,used of course .
