Search “Silversmith Fidelium” on the Forum. You will see that Pretty much everyone who bought them say the same things. That they are the best they have used. I replaced very fine $6K speaker cables that are now relatively junk in comparison. For $1200 an eight foot pair, they are one of the best bargains in the biz. I agree that there is a synergy when using all the same brand. Silversmith will have IC soon if not already. Even if you don’t get the new ICs, get the Fideliums.
There is also a trail period.
