Jw944ts, for my system, the Fideliums were … “transformative.” I expected some improvement over the quality cables I had (Mogami cabling, custom made) but I was shocked by the massive improvement in both imaging and tonal qualities. I recently sent my monoblocs off for upgrades and had to use another amp (Rega) and cables to drive the Fynes, and the soundstage simply collapsed—I know the amp is also responsible. I have gotten the amps back (as 2 x stereo to vertically bi-amp the Fynes) and have received needed adapters from Silversmith and will be restoring everything into play tomorrow—with two sets of Fideliums!. For me, the Fideliums were a total game changer and are now indispensable. Heck, even my Shetland Sheepdog notices the difference. With the Fideliums in the system, he goes to the general area of the speakers to bark at some songs. Without the Fideliums, he goes right up to the speaker to bark at it.😎 … but true.
