I hate to burst your bubble but I doubt anything is going to change those Spendors. I have owned many Spendors and they never had an aggressive high end. I would say that the newer D type Spendors are the problem that you describe. I think you will be spinnin’ your wheels changin’ gear. BTW, I always liked any Spendor that I’ve owned!

*Spendor LPZ (Linear Pressure Zone) tweeter*
The goal of every tweeter designer is to achieve linear acoustic output over a wide frequency range. In practice this is extremely difficult. Spendor’s approach to this age‐old challenge is radical, and it works. The Spendor LPZ tweeter is built around a stainless steel front plate which forms a damped acoustic chamber directly in front of a lightweight woven polyamide diaphragm. The front plate incorporates a phase correcting micro foil to equalise sound wave path lengths across the diaphragm surface, simultaneously it generates a symmetrical pressure environment on both faces of the tweeter diaphragm so the tweeter operates in a balanced linear mode. The front plate also provides excellent mechanical protection for the delicate tweeter dome and a smart modern appearance. Imagine focusing an ultra‐high quality camera lens until you see a clear bright image. That’s the effect of Spendor LPZ technology. Our sequential geometry micro‐foil operates like an acoustic lens. The result is perfect focus, uninhibited sound transmission and a very wide listening window. Sound images are vivid, in‐the‐air, as bright or sweet as any music demands.
