Nordost flatline vs. A-Plus+ Oval12

ANy thoughts? I have a very silky smooth system...however...I am craving a tad more definition ...leaning towards NOrdost...
Hi . Recently had Nordost Blue Heaven speaker cable in my system driven by modest SS power. After purchasing a friends Cardas Neutral Reference cables I was impressed. The Cardas cables were the equivalent of a component upgrade. They added way more authority and just let more information through to the speakers.

Both brands of cables were bi-wired. You may experience good results with better Nordost cable. I understand Nordost flatline cables work better with tube amplification. Cheers.
