cable break in

>>Break in takes about 2 weeks average playtime<<

NO NO NO. There is no "average" time for cable break in. It depends on the conductor, conductor geometry, and dilectric. It's different for all cables. Same thing with "biggest differences"; some are linear, others are not. Ask any cable designer.
Your opinion is erroneous and misleading. Readers should take it as your opinion as it is not based on any empirical data.

Stanhifi, you can also say that any break in time is entirely an opinion and not based on any emprical data, as you put it.
Dave B's opinion of 2 weeks average time is no more erroneous than your opinion that there is no "average" time, and no more misleading than yours.

Stanhifi...do you listen to music or just measure it and talk about it! I've most likely owned more gear and cables then most. I have also talked to many learned audio guru's/owners of cable companies...most would not agree that over 2weeks of 24/7 break-in is beneficial. Most cable designs offer mostly inconsequential differences in the sonic presentation...not overall fundemental improvements. Everytime I have heard a properly setup system with MIT cables, the experience was nothing short of breathtaking.

"Most cable designs offer mostly inconsequential differences [after break-in] in the sonic presentation . . . ."
That has not been my experience, and it has not been the experience of other audiophiles I know.
