There’s no question in my mind that the CW IV crossover can be easily bettered with more substantial parts. The caps and resistors are run of the mill. Careful here--I’m not saying that leads to run of the mill sound. See my post on modifying the Carver Crimson 275 amp. Bob used some decent and some dirt cheap parts in it. The coupling caps in that thing were the size of my pinky fingernail. They are inexpensive and not of good quality. Can they sound ok in a good circuit? Sure. Same thing with Klipsch CW IV.
I’m not saying folks should do this to the CW IVs. But, I will venture to say, and I’ll bet DonSachs would likely agree, many folks will question what he and I have done here while they are out buying very pricey power cords, interconnects and so on. This upgrade will best all of that in my humble opinion.
My CW IVs are about 100 hours in or so. They sound glorious. VCap ODAMs are really special caps. They almost sound like the cap is out of the system.
