Kef 107 Crossover Rebuild


I am interested in a pair of Kef 107 speakers. There is a pair which had the crossovers rebuilt with Jantzen caps instead of caps from Falcon. Any idea how the Jantzen caps will sound compared to the Falcon caps. Will the sound quality be sacrificed since they did not use OEM caps. Any feed back is appreciated.

They’re likely to sound different.  It’s always subjective, but my experience has been that I’ve favored the improved clarity of a good poly cap over an electrolytic.  They tend to take a while to burn in, and some folks get discouraged with the sound early on before they come around. 

If a search is done, Jantzen Caps will be discovered as upgrade choices over certain components. 

Some Speaker  Kits use Jantzen and these kits are known to comfortably compete with Speaker from Brands that cost the price of a decent car. 

I'm no expert in the choice of caps based on sound for speaker crossovers.  Polys do seem to be preferred in amplifiers, though. 

However, electrolytics are known to degrade over time:

You may wish to replace any electrolytic caps in the crossover with a different capacitor type when upgrading.
