Per the series II manual, you can hook from preamp output to EQ input and EQ output to amplifier input. This avoids the tape loop. On series II EQ, you have both options but with separate amp and pre, it says not to use the tape loop. I don't think I ever tried it that way and could be why I hated the EQ. I'll have to look at my series VI EQ but I'm sure the same applies there. Interesting thought that I may have used them the wrong way for so many years. I know there are tons of people out there who will say that there is no right way to listen to them but most of these guys never heard them correctly. I'm sure they will disagree but...........whatever.
Don't know what series you have but foam surrounds tend to go bad on series 4 the worst. They had a buy back program and put people into series 6 for a huge discount. I bought a pair of junk 4's just to trade in and got my 6's that way. It was $400 for the trade with Bose. I think the retail was around $1500 at the time.
