Tweaks that other members of family noticed.
When I change a cable or use some Isolation product or some other tweak (with out the knowledge of others)---
Some times only I do notice a change, some times I do not, but few times members of the family noticeda change as the change is not subtle.
Here are few
Replaced (borrowed.) cardas Golden reference cable between pre and power amp.
Comment -It sounds different than before and better
Probably the warmth of the cable is the factor
Replaced Aural thrills cheaper gold alloy cable between Satellite receiver and pre amp
Family members noticed a change
Added Boulder bybee RF video adaptor for the satellite cable.
After few days allowing for break in
Without any prompting” the TV picture is getting better, more clear”
please share your experience
