On same page as you. Actually I have my Advent 1's still with me that I bought in 1980..they sound great and would not want to fiddle with them. Perhaps another pair in need of tweeters would be the impetus for that project...
The 1's have never sounded better with a little room treatment and Carver M500t amp and NAD pre with tube pre buffer between the NAD and Carver.
The Advents have wonderful bass and being a Bass player has always been my thing with them.
