xon501:Do you think it will benefit to change it with a crimson, as 5m is too long and I fear getting to much cables behind the rack, so need a shorter one and hope that in the process it will be a better one.
Impossible to say without doing a comparison between the two I'm afraid. However, if the main driver is to get a shorter cable, it can only be a benefit if it does sound better. Just make sure you don't get carried away on ebay and pay too much - brand new 3m Crimson cable looks to retail at about £26 - £27 including delivery.
