Spendor s3/5 upgrade recommendation?

You might try the Spendor group on Yahoo. See:

However, speaking in general terms, Spendors are thought of as a very well-thought out design with very appropriate component selection. One typically doesn't see much in the way of mods being recommended or suggested.

Roxy54, there was really nothing to "disagree with" the others in what you did.

First, I don't consider the replacement of aged or degraded parts a "mod." That's just prudent maintenance in my book.

For me, a "mod" is when the original crossover point was 3 KHz or had a 12 dB slope and someone decides it should be 6 dB at 2.5 KHz or a similar deviation from the original design.

Second, you have an older speaker that hasn't been in production for a number of years. The S3/5 is still a current production model. His unit could be up to 10 years old but his question didn't give that impression.

Lastly, no one said DON'T mod the speakers, only that it isn't often done, especially in contrast to many other brands on the market.
