Er you go m8
Thank you, horsey.
Based on experience, silver cables + Grado drivers are not a good combination. Consider staying with copper for a neutral presentation.
Being that Grado headphones are very good on the detail, the silver cable tends to add more "sizzle" to the upper end. It's not a good pairing and since silver cable costs quite a bit more, you are much better to invest your money in something else.
Again, this is my opinion but is also backed up by many members who have heard the combination before.
I have a set of Beyerdynamic DT-990 drivers for transplanting. I'm thinking of trying them in a set of Grado woodies. The drivers are 45 mm in diameter and 8 mm "thick."
The PS-1000 drivers appear to match the diameter but how thick are they?
