However, I was told that Lyra was designed and tuned with copper wire in mind (don't know how true this is though) so I definitely want to try that.
from the signal transfer ability Copper is 100% in its highest, purest availability (Audio Engineering Society) so that is the Standard based on AES
Silver has 106, that means, no other material on our planet can carry more than silver, 6% more than copper, 16% more than gold and I think, more than 45% more than brass...
Some cartridge manufacturers know that and use silver plated pins, some audiophiles know that and use silver headshell leads + plugs, some Arm manufacturers know that also and use silver internal Arm wire, some cable manufacturers know that also and use high quality DIN Plugs ...makes some sense for the ultra low MC Signal....my advice for that is, think about that, check your Cable of choice and also the used RCA connectors (most are inferior, even in combination with very expensive cables) and of course, the quality of the RCA jacks from your Phonostage.... :-)
Normally any Signal is degraded here seriously....MY Pods are $200,-- for example, not the usual $8.95 ...
Good sound is based on knowledge about what is responsible for what ...
