Mogami wire quality?

Joseph Levy of Tempo Electric told me the same thing the atmasphere stated. 4 nines of anything is all there really is unless you get into exotic jewelry (the kind you wear). He went on to say that it's actually 99.975 for silver due to the fact you simply can't get all the impurities out during manufacture. The same may hold for copper as well.

All the best,

Sounds like the Mogami cheer leading squad has entered the building.

Actually, rja, it's the newly-converted.

A cable like mogami is certainly much better than let's say a Dr Morrow, or Kimber, or audioquest, because in the mogami, you get a good chunk of pure copper kept all together whereas in the others, the cable is made of individually wrapped smaller conductors, therefore a lot more plastic and copper in contact with dielectric which is bad.  It 's actually so bad that audioquest felt the need to slap batteries on their cables.
Dr Morrow is more plastic than copper.  I don't get it.
