Someone asked a question earlier in the week ...about if there was another way of telling if the unit was creating an effect ...other than the blue tell tail  being on.......

on several occasions the unit has created a slight discomfort in certain listeners...ian found it "jarred his nerves"  I've felt as if I'm going to get a headache ...sq225917  felt his sinuses effected .....

of course these are anecdotal in the extreme   ...I certainly don't feel the effect each time I set the unit up ..  but often enough to make me wonder....

other than that   and of course hearing your system sound better than it has ever done   I don't know......

As to setting up a measuring session .....sound interesting   has anyone suitable fascilities  that isn't hundreds of miles away ?

still had no invites from the "none believers" [except tenson who's too far away]
