I am happy owner of 325is's and to my ears they are not bright as most people are saying about them. Not burnt at all yet, but I will let them to be soon. One question I have. Is it worth to think over the cable change? Does it bring a lot of benefit to change it at all?
The new large cable with the 325is is very adequate unless you don't like the size and weight there is no real reason to change the cable.
It is the same cable that comes with the most expensive Grados.
