Biwired Speakers - silver for high, copper for low

I formerly used Alpha Goertz big shiny copper ribbon MI-3 for excellent full range results, including body, detail, and transparency. Then added for the upper treble range, silver ribbon AG-1, with bi-wiring. Similar to your speaker cable search. By using cables from the same company, I did not feel any problem with integration of different parts of the audio spectrum, and there was an overall perfecting of the sound. I cannot tell whether WAF allows for ribbon cables.
My current cables are Gregg Straley's custom single wire cables, which are the best to my ears, very low cost, and come with money back guarantee. They are coated with an attractive finish in the red spectrum, so cannot know whether they appeal to the fashion police, in your household. Omega Mikro are out of my league price-wise, and are probably more exotic than you really need to achieve satisfying sound.
I found all the attributes you mention, by switching to a single cable, so the copper-silver debate is not the sole factor in achieving system synergy. Nor is going exotic, with its more demanding set up constraints in a room shared with rest of the family.

You might consider trying the new Flexygy 6 cables from River Cable. They are flat like Nordost for WAF and have a nice, neutral sound with good body. They offer a 30 day money-back guarantee, so you have nothing to lose.Plus their price is very reasonable and affordable. Their website is www.rivercable.com Just click on the Flexy logo. You can order directly from their site. Good luck.

I would temporaily switch out the Poemia and put it on the bottom. You may be surprised with the bass capabilities. Then if you like it , just get another pair of Poemia's.
I originally was kind of thinking like you and was going to use AZ Sen Satoris on the bottom and Poeima's on the top.
I now have bi wired Poeima's {shotgun} and Im very pleased with the results. I cant swear to it , but I beleive the sound is quicker on The Silver Poeima's, which may explain why you are hearing a phase shift.

Thanks for your response guys.

La Fashionista is not that bad. She complains about the monsterous Shunyata and Electraglide power cords, I hide my credit card bills well. All's fair ;-)

Once in a blue moon, I get a remark along the lines "this sounds good, what did you do ?" Most times, I am allowed a free run. I can't however have extreme stuff because of two highly intelligent and extremely inquisitive juvenille life form.

Listener and Sherod, thanks - I will look up your suggestions.

Darryl, I have tried the Poiemas on the bass. Doesn't do it for me some how ?? I have spoken to Mnh and Robert @ RSA, for some reason the Poiema has not sung for me yet. Don't get me wrong, The Poiema is great sounding, I thought the delicate portrayal is to die for (as far as refinement goes). However, I do like a bit of the rougher (dynamic) side as well. My Poiema so far has not revealed that side. I don't think it is my source or pre-power. I will try again after a few days - it may simply be a question of extended setlling in.

Hi Tom, you should consider several factors in your cable search. First, you have not posted your system. If you do, chances are better you will get some more specific recommendations from those who have the same speakers and components. Second, you should consider where the speaker crosses over. The designer of your speakers was sure to consider the tonal balance between HF and LF if a bi-wire option was provided. If the LF is simply a "subwoofer" in that it operates at a very low frequency (e.g., lower than around 100-200 hz) then the differences in cables will be less important. However if the crossover is up in the lower midrange area, you are likely to muck up the tonal balance by using different cables, especially ones as different sounding as silver and copper. My general suggestion is to find a cable you like and use two runs. Some manufacturers make a lighter gauge cable of the same materials, with the same sonic qualities, that you could use for the HF while using a larger awg cable of the same make for the LF. You could consider internal bi-wire from someone like Cardas, which tends to throw a lot of copper into their higher end wires. If on a budget, the Jon Risch CC89259 diy cables are quite neutral and would offer that dynamic sound you are looking for. You could even go with the "quad" version for your LF if you wanted that last bit of bass. You could also consider trying different options from The Cable Co. Good luck. - Tim
