The question I started this thread with is now is irrelevant as I have been to Electo Sound and now have a pair. I would like to just say a big thank you to all that have contributed and kind offers of a demo.
But alas another question which I will be contacting Electro Sound about is when I demoed them there was a lot of buzzing with the speakers. He put this down to me using a laptop with an external sound card and placed a DTI filter which seemed to cure the problem but on setting them up at home the buzzing is still there but not as bad gets worse when you take the filter out.
He said that he has come across this before and a DTI filter may solve the problem but suggested a bet quality sound card my cure the problem the sound card by the way is a creative sound blaster audigy anyone got any thoughts, ideas, or suggestions
is the DTI filter not a ground loop isolator
Dual transfomer/isolator which is a ground loop isolator
cant see the hum being a problem when playing music but for any speaches could be a pain
You live and learn.
And are you sure it does the same job?
HHve youtried taking the mains transformer out and running on battery - if the noise disappears you know its the ground loop.
Then maybe it's worth looking at a better card which is made for the job rather than a generic sound card.
