I’d opine that if the new IC’s made a “huge” and “dramatic” and “night and day” improvement, you must have been using very old, beat-up, falling apart RCA pairs that were smeared with butter and Cheetoes.
An upgrade to expensive wire should make no difference as long as you were previously using Monoprice quality cables or better. Even those that believe that expensive wire can make differences mostly agree that the improvements are subtle.
Are you by chance a dealer of these products?
