What's Next

I recently had a home audition of Shunyata Sigma, Audience A24 SX, Clarus Crimson, and my Wireworld Silver Eclipse 7. I preferred the Clarus, followed very closely by Audience. In my system the Clarus provides the best detail without being forward, presents a wide and deep soundstage, and great front to back placement.  
My interconnect cables are Audioquest Fire XLR and my power cords are Wireworld Silver Eclipse 7 with Platinum plugs. I recently compared Shunyata Sigma power cords to the Wireworld and decided to keep the Wireworld.
Cables are really a crapshoot and the only way to know what's best is to evaluate them in your own system. The problem is there are endless combinations and it's impossible to evaluate everything. 
 

Are there any Clarus Crimson speaker owners on Audiogon? If so, what  other cables have you compared them too?

Here is the problem the AQ Fires we did a direct test vs the Wireworld and the Wireworlds Platinums were way better. Also the Wireworld Silver Eclipse power cords are okay at best good for the money but a reference grade system such as yours needs better cables.

Again, everything is system dependent... Surprise...I had Wireworld Platinum in my system and compared them directly to AQ Niagara and preferred Niagara. Since the Niagara isn't current, I decided to get a home audition of the Fire. In my system the Fire had more detail without being bright. I submit my system is neutral to the dark side of neutral and the Wireworld made my system sound too dark, consequently I lost details further in the soundstage. 
Honestly, after hearing the Shunyata power cords(that are supposed to be significantly better than Wireworld) I'm content with my power cords.

I did compare the Audioquest Diamond USB cable to the Wireworld Platinum USB cable. I preferred the WW, because the bass was more articulate, soundstage was bigger, and just a more natural and detailed USB cable.
