UCrewX5 and Tom G.,
The repair notice worked like a charm

...hiss is eliminated!!!
I want to thank you both for your contributions. The icelink now seems troublefree and enjoyable to use!
If it were not for this forum, I would have got a refund long ago. It's too bad the installers are not educated, and the current Dension support is not responsive with these fixes/tips along with making info readily available to consumers (i.e. Dension web-site support).
Guys, much thanks again!!!
