Tvad's ISOMAX transformers arrived today. I tried them using the KEF Model 200 KUBE that had previously caused the sizzle. The result was flawless: Silence at the speaker, and, even though designed for use with a different speaker, the KUBE provided substantial LF extension. I played the Ondine SACD of Saint Seans 3rd symphony. Pedal notes that were inaudible with the unaided 104.2s became audible.
Had I known the KUBE was so effective, I would have looked for one tailored for the 104.2s. Anyone have a lead on a KUBE for KEF 107.2s?
