I have a pair of Paoli 60M’s and a Pas 3 that i got over 30 years ago from a good friend, along with other solid state AV equipment that I’ve acquired over the years, all plugged into the same 20-25 year old Acoustic Research power bar. The bar probably needs replacing and was wondering if any one has recommendations that would both protect the equipment and not adversely affect the sound quality or may even improve it.
