What is the future for Proac Speakers ?

Stewart or any others that are familiar with ProAcs.  I demoed some Tablette 10s that sounded amazing a month ago.  Finally made the plunge and bought some.  However they sound incredibly muddy right now.  Especially the vocal tracks (almost sound underwater or in a tunnel).  I have read that they will take a while to break in.  I have never had to break speakers in before.  The PSB Image B-25s I upgraded from sounded ready out of the box.  

I have Ave been trying to run the speakers while at work but my Appletv keeps cutting off so I have no idea how many hours are on them yet I have played maybe 15 hours of vinyl and normal tv with center channel set up.  I'm guessing 30 hours of total music time.  Starting to get a bit nervous with the purchase.  What is a reasonable amount of break in time in which I will finally hear a noticeable positive difference and real separation of instrumentation?

My setup is not ideal.  Speakers are in a custom built cabinet into the wall.

137 inches tweeter to tweeter.  About 3 ft off the ground.  Isoaccouatic stabilizers (medium size) angled upwarrds.  119 inches to prime listening position.  Ears probably at 4 ft from ground.  Left speaker is completely visible and right is partially blocked due to cabinet Co figuration.  I will upload pics as well.

Thanks for all the input.  The will incorporate what I can.  What is intwrest No though is the pair I demoed has all the same equipment and placing limitations I am working with now with the new speakers.  The am sure they will sound better with suggestions but still concerned they do not sound as well as the demos I used for 4 says with same set up.  Someone mentioned 150 hours for break in.  I am at about 96 hours now so will hold off on panoc button for another 50. Sound seems to be improving but vocals still sound muffled.

Just an update.  Speakers broken in and everything is top top.  Thanks for all the help.  Posting was the issue as well.
