How long for an HDMI cable to break in.

I simply put it in and did not pay attention to the direction of the Blueberry so it was the wrong way.

It bothers me that I put this Vodka in and it made no difference whatsoever. In fact it sounds a bit duller than the Blueberry. Again it may take time to bloom. But 
I feel like wanting to take out the pricy cable and put the cheap one back in so I don't waste time listening to music where I'm not enjoying the sound as I did before. When I first used AES and then the HDMI Blueberry there was immediately a big jump in sound quality. 

5,000 hours is the typical time for audio HDMI.

4,000 hours is when things begin to bloom. 

You can hasten the process by using it for video and audio simultaneously. 

Are you sure??? If you use it non stop 8 hours a day it will take 625 days - almost 2 years......

Did it improve the video or are you only using it for audio?

Audio.
