Mogami wire quality?


Say compared to Cardas? 
ptss
Mogami is really, really good for i/cs or speaker cable. If interested, I suggest you contact 10audio or zenproaudio who are Mogami experts. They can advise you as to the appropriate Mogami cable series for your i/cs or speaker cables (very nice folks as well).

Mogami W2552 is also good for headphone cable. Cardas 4x24 is my favorite for headphones.  If on a very tight budget, Canare L-4E5C star quad is likely to be an improvement over most factory supplied headphone cables.

Just saying ...
Even if one wants to pay more for boutique cables in certain applications, the Mogami Gold Studio balanced cables are an insane value at about $40 for a 3' pair (from Sweetwater, Musician's Friend, Guitar Center, etc.). Great for subs, surround sound, home theater, systems with Atma-Sphere electronics ;-). 

Also, the wire material is basic OFC copper that is stranded. All this is decent for what you get. They are generally less expensive (under $150 in most cases, unless you are getting a multi-channel snake or something).

Cardas has a very specific manufacturing method where it uses a very high purity copper

Just a FWIW: if anyone tells you that their wire has greater purity than 99.99% (for example the myth of 'six-9s' copper) turn around and run as hard as you can.

No-one anywhere has copper purity greater than 99.99%. This is due to the facts of extrusion- you can certainly start out with something more pure, but by the time its actually safely in the insulation its no more than 99.99%.

99.99% is what is known as 'OFC'.
Just watched a video link in a thread for a Moon 888 amp . At the end Micheal Fremer asks what the wire inside this $120,000 mono amp is.  Guess what it is ?
