I left the above review a week ago and then, following a number of posts, promised frank that, if I did not sell them, I would do a further review after "burn in". They have been in use playing CDs and Radio 6 music for the whole period since. I have listened to them for at least 2 hours a day whilst the process has been ongoing. My final comparisons this morning lead me to the following and genuine view. The cables are noticeably less "brittle" and smoother. But the sound remains also noticeably drier than the stock cable and has less presence in the midrange and bass and still detracts from the organic quality of the LCD3s. It may be a question of personal preference, but there it is. If anyone would like to purchase them please let me know.
Hey, you gave it a shot! Personal preference is always going to play a large part in any audio equipment purchase. I'm guessing if you post in the classifieds here, they'll get purchased pretty quickly.
