Seems to me what we currently see from twevy is being afraid of manual 
dispersion due to all and sundrey being given the op****tunity to 
actually discover just how old and crap the me design has become in 
relation to other  more modern amps thus destroying the perpetration
( in his lunchbox) of thier "speshulness"
  Wilson your a dick and if you tried this ****e in my trade you would 
be finished in a week .Still no fear of that atm considering just how 
thicke you have been proven
