I was wondering when/if anything would come of this:
If you go checking again then look at the Infinity Interlude IL10 bookshelf speakers on your Craiglist
I think you were busy looking for parts for your $15/pair 7T's!
I am enjoying this thread!
Your 7T's certainly turned out as an easy fix and you should see a pretty good return on investment when the time comes to sell them!
Also enjoying finding out more about which of the older speakers might have value. After around 1980, I only started listening to speakers for fun about a decade ago. I don't think Zeig ever stopped!
I can say from a sound quality standpoint avoid any Japanese speakers prior to the '80's (I'm sure someone will be along to point out an exception soon enough, but I'm still going with it).
I believe you can still restore and flip them for good money because I know plenty of people who are really into and will brag about their vintage Pioneer/Sansui/Sony/etc speakers! However, for whatever reason, despite totally kicking a$$ in electronics, they just never got speaker design. Those Sansui's look cool with all of the drivers and controls on them, but I'd take a "modest" KLH 6, AR 2ax, EPI 100, Small Advent, or Dynaco A25, over them any day of the week!
