We are kind of in the same situation. We have older technology that we would like to keep: JVC 200 disc CD player and Pioneer amp/receiver. The amp has a headphone jack, but it's the larger size - not the 3.5mm or 1/8" connection. We would like to get rid of the larger speakers and get some wireless speakers around the house. We were thinking bluetooth but when we spoke to a guy at Best Buy, he tried to convince us to change everything to Wi-Fi technology - that would be too expensive for us at this time. Suggestions? Is there some kind of connector/adaptor that changes from the large size headphone jack to obtain the female end for the 3.5mm transmitter?
