Speaker Cables? why all the hype for expensive speaker wire?

The only way you will ever know is if you try it out for yourself. The cable company offers a trial plan.

The reason why I invest in cables, is to attempt to get the best sound replication possible. I accept the fact that I am not a sound engineer . I know what I like regardless of price. The more expensive the cable, the more due diligence I do - which for me can take years. 

After careful consideration, if I am able I will make the investment - in what translates to my happiness which to me is priceless. A portion of that investment goes towards peace of mind, Accountability/ trust in the company producing the cables. Almost all of my purchases have been on the Used Market.

This said - I have witnessed first hand those who believe that they know more than the companies who design and manufacture cables (because they took an engineering course in college 5,10,25 years ago).
- In EVERY case it never ended well.

GREAT Power Cables, not a fan of the Speaker/Interconnect cables

Lot's of good inexpensive speaker cables out there.  That said, I definitely heard improvements when I recently moved from my Acoustic Zen Satori to my current cable, a Nordost Tyre 2. IMHO need a pretty high resolution system and a good room to parse these kinds of things out.   Most of the differences I experienced with this last change were somewhat subtle.  Nothing night and day but I haven't tried lamp cord or 14 guage romex or anything like that so I can't compare my current set up to something quite that bare bones.  Another issue here is with the listener and how trained their ear is.  I have been playing music for 50 years and have classical training.  It really does help me unravel the music and I believe makes me more sensitive to nuance.  In the end, whatever makes you happy.  If you hear a difference no one can argue with you, if you don't hear a difference, no one can argue with you.  No one can make you hear what they hear and the fact that you don't have the same experience doesn't invalidate their experience.  

So here is the question I have been pondering. If speaker cables make a huge difference, and there is a range of cable for each brand, why is it I can’t find a dealer that will take the time to run multiple A/B comparisons within the line they carry. It’s like buying a car before you even test drive it. Just taking the dealers word. I would think they would sell far more high end speaker cable if they had a cabinet of demo model cables for all the wire lines they carried. This way one could listen to the full array and make a good decision. 

focker you make too much sense for this forum.  

It's a valid question. I have had Straight Wire Crescendo speaker cables(and interconnects) since 2009 and they are very good. But I've been contemplating an upgrade.

It took me a long while to sift through all the different speaker cables and their claims and reviews and I still couldn't make a decision.
Then I started looking into Townshend's F-1 Fractals as I was buying many of their vibration isolation products.

The reviews I read about the F-1's were on the side of revelatory and I was very interested in how they treat the copper wires with the Fractal technology. It's a different type of copper wires in a way.

In the end, I bought a pair of the F-1 speaker cables and even their F-1 interconnects to replace my Crescendo interconnects to keep the same loom. I should be receiving all the isolation podiums etc and Fractal in a couple of weeks.
