Speaker wire... Diy?

Cables interact with the system. There is no guaranteed better. All the various geometries are tone controls. They may sound well in one system/room, no different in another and terrible in a third.

A large reason for the lunacy of the audiophile world is ill educated consumers taking recommendations from ill educated sales persons. Many people have no idea how to assemble a system. That includes most dealers.

NEVER take any recommendation from anyone, anywhere that does not have an identical system, room and TASTE to yours. Only make cable purchases that have OHPNQAMBG - One Hundred Percent No Questions Asked Money Back Guarantee.

For examples of how the same cable reacts with different loads and how different cable reacts with the same load see http://ielogical.com/Audio/CableSnakeOil.php. Be sure to read Garen Galeis papers.

Just get some Duelund 12ga

Talk about overpriced low tech. Little different than THHN 12ga @ 50¢/m.
It may sound a little different, but unlikely better.

Helix Cables are utter nonsense, as is the verbiage on the web page.

The same current flows in all parts of a circuit. The -ve terminal may remain @ 0v relative to earth ground, but it is positive relative to the +ve terminal over ½ cycle and thus current is flowing out of the -ve terminal re conventional current. Electron flow is in the opposite direction.

They will sound different, maybe better in some systems, but their 'science' is flawed. Good amplifier designers try to avoid additional inductance in the output stage. 

They are simply more inductance, a LOT more - maybe 2000x more than zip cord, in the -ve wire in a sort of transmission line geometry.

Scroll down to  Amplifier Output L and R in the middle of http://ielogical.com/Audio/CableSnakeOil.php and see what adding a few µH does. Image what 5mH will do!!!

Audiogon...where experience means nothing.  Happy delusional trails!!

Dave, you may like a particular cable in your system in your room on your program. Fair enough. But I could come over with my program and be underwhelmed. Ditto you here.

I have bins of cables in the garage. Every so often I swap out a set. All have varying strengths depending on the program AND associated equipment.

I recently pulled my Transparents in favor of some old Monster and Hitachi StarQuad when I changed bottlerockets from 36w stereo to 125w monoblocks and Kimber BiFocal XL.

My experience is only worth a sou on my system in my room and my program at that moment in time. I would never presume to recommend anything based on my experience, other than to recommend ignoring all advice and listen for yourself.

I almost never make system changes in the summer months as I listen more in the winter. The colder weather and dryer air affect the sound dramatically relative to the summer.

@soix Solid is far less flexible, hard to route and will eventually break if flexed enough. If you like the sound and are willing to put up with it, go for it.

Have you tried them? obviously not

Many others around the world have tried them and prefer them to commercially available products.

I leave it at that :-)

@williewonka 
It's entirely possible that the Helix cable could make someone prefer their sound. I just can't imagine what the system sounds like sans 5mH in the -ve lead.

Some eat MickieD's. No accounting for taste.

That’s why these cable threads have been going on for forty years with pretty much the same results.

mostly due to trolls that ruin the experience. Moronicity is seldom humorous. Tedious, definitely.

@ddjr - it is entirely possible with your gear that you do not hear any difference. With other gear you might.

@dave_b 
All speakers are colored and far from neutral.

I have a pile of Transparents, some of which I used for more than 15 years, currently 'resting' as they did not complement my monoblocks.

Transparent makes great cables, but I refuse to drink their, or any other manufacturer's, Kool-Aid and reserve the right to use something different to ameliorate exacerbated flaws.

I'm interested in getting music to sound as good as possible.

Go to a live acoustic concert. HiFi is a 1% solution.
