I’ve found changing out caps can make a nice speaker sound much more enjoyable. I started out with Sonicaps there cheap and if no improvement it wouldn’t break the bank, there was a fair improvement.
After a few months I pulled them out and replaced them with clarity cap CMR’s. This was a big improvement. I then bypassed them with Miflex and Duelund with another nice improvement. The Clarity CMR’s are big so I just built the crossover outboard. I also changed from Mills to path resistors another nice improvement. I also tried the Jantzen Aluminum z’s they were nice, I even mixed and matched them with the CMR’s. I also tried the Vcap odom’s in other components and would like to try them in some speakers.
My other speakers sound very good so I’ve just left them alone but still would like to put better parts in but just haven’t and probably never will. Playing with caps and internal wiring is fun and very rewarding but where does it stop.
