Clear Day vs Acoustic Zen

And what is keeping you guys from ordering a free demo set from Paul at Clear Day? All you'll pay is return shipping - which should be less than $10.

Well I have not heard the Clear Day cables, but I have seen that they use silver conductors. I have heard many cables that use silver conductors, and I have owned the Satori Shotgun speaker cables. Both can be very good in the right system, but you would need to decide which way you want to go.
You say that the B&W are generally considered bright speakers, but the question is: Do YOU think they sound bright? It doesn't matter what others think.

That said, the AZ Satori is fuller, warmer, with bigger bass than any silver conductor cable I've heard. However, silver can also sound very good in the right system, more revealing, more definition. I actually have a couple of AZ Absolute power cords and a pair of Absolute interconnects, which sound better in my system than the Satori did. Absolute is a mix of silver and copper, but probably out of your price range.

If you are looking for musicality, full bass, and warmth, I would recommend the AZ Satori. If you want higher definition, more transparency, I would look for a Clear Day trial. Very different cables that can both work well with the right gear.

@jmcgrogan2  - First of all thank you for the detailed response. This is very helpful. So as far as my speakers are concerned, I feel that they can be a little on the bright side on certain songs. Also, sometimes they sound a bit more on the 'thin' side than I'd like them to be. I understand that a lot of this has to do with the acoustic properties of my living room, but unfortunately, there's not much I can do about it. Wife shot down the idea of hanging treatments on walls.

If the Satoris are 'fuller, warmer, with bigger base', as you mentioned, then that's exactly the qualities I desire in my current setup. At some point, I'd like to introduce a tube pre-amp in the mix but that's probably not going to happen for at least a couple of years.

I'd keep my eyes open for pair of used AZ Satori (8 ft or less) at agon. 

Some people feel all silver cables are good with tubed electronics, copper with solid state. But Cardas and Audioquest copper are used with ARC and other tubed amps at some dealers, so there are differences of opinion. Big surprise!

 That is because some tube gear sounds warm, while other tube gear is revealing, just like SS. I own a ARC preamp and Pass Labs amps, and I would say that the SS amps are warmer sounding than the tube preamp.

@arafiq , you are welcome.
Look on other websites too. I see a 8 foot pair and a 6 foot pair of Satori for sale on US Audiomart. The prices are a bit high, but you may be able to talk them down. I believe the 6 foot pair is new, I think that is a dealer. I've seen him sell a LOT of AZ product.
Use HIFIShark when looking for a certain product. It's a search engine that searches through ALL of the marketplaces, not just Audiogon or Ebay.
Happy Hunting.
