Vintage KEF vs new Salk

As I stated in your other post, your KEF Reference Model 3.2s are fantastic speakers and would be hard to beat. The Salk speakers are very nice sounding speakers with wonderful cabinetry. However, they have a different sonic signature compared to the KEFs. Personally, I prefer the KEFs but your experience may be different.

Your KEFs are easily refurbished. The midrange drivers have rubber surrounds and do not need replacing. The internal cavity-coupled bass drivers also have rubber surrounds and do not need replacing. However the donuts on the bass drivers are foam and might need replacing. The donuts in my Reference Model Ones and Twos are still fine. The major item that should be replaced is the ferrofluid in the NT25 tweeters. Several people have done this with pictures on Audiokarma. I have not done mine yet. I did replace the ferrofluid in my KEF 104/2s and it was a simple job and took about 1/2 hour for each speaker. The caps in the crossovers may need replacing but I have found that they are typically ok with these speakers.

You stated they need refurbishing. What doesn't sound right with them? Typically it is the high end getting dull when the ferrofluid begins to dry up in the tweeters.

Marc,
I am not sure what is making the fuzzy sound in your left speaker. It could be the tweeter or something else. 

The bottom front driver is the lower midrange driver and the upper front driver is the upper midrange driver which is the Uni-Q driver housing the tweeter. On the Uni-Q driver it would be hard to tell if the fuzzy sound originates from the tweeter or woofer. The NT25 tweeter is a tight fit in the center of the midrange driver and maybe something is misaligned.  

If you look in the front port with a flashlight I think you can see one of the woofers and check if the foam donut that goes around the coupling rod is degraded.

The four-way crossover is assembled on a large printed circuit board which is mounted on the reverse of the plastic rear terminal housing.

Regarding taking them apart, I believe there are some examples from people who have done it on Audiokarma.

Regarding the Salks, I would not rule them out. They are fine speakers. The best way to make a decision is to hear them for yourself. Any move you make will be in uncharted sound unless you can audition them.

Marc,
I forgot to mention that the front polymer baffle housing the two midrange drivers is removable. There are 6 screws attaching it to the cabinet. I think they are hex head screws but might be torx.
