Anyone have experience with "burn-in generators"?

No personal experience with the "Burn-in-generator". I do not think that I would use one anyway. You should Know within two weeks if you like the cable or not. What you get with more time is a refinement of the basic cable qualities. In other words, if the cable sounds good and makes a positive contribution to your system, it will only get better. How much better will vary from system to system and much of the perceived improvement will be very personal to the listener.

I would prefer to break in cables with a break in cd or use the repeat function on your cd player.

I've had a Hagerman "Frykleaner Gold" for years and wouldn't be without it. Neither, it seems, would my audiobuddy friends, who have borrowed it a lot :-)

Light them on fire (?)

having auditioned many cable sets, as a reviewer, i can say that sometimes the initial impression of a cable, changes with break-in. on several occasions i have liked a cable out of the box, only to change my mind after 300 hours. in two cases i went from liking to disliking a cable.

so , i would say, reserve judgment until after break-in.

Anyone know exactly what is going on within the cable during a 500 hour 'break in'? And how is the length of 'break in' time determined? Just seeking to expand my knowledge.
