I’ve been living with the Espirit cables for several weeks now. Due to Covid, we’re spending a great deal of time at home. Therefore, the stereo system gets a lot of hours. I’m sure the new cables have been broken in. Unfortunately, since the process is gradual, I really can only comment that I am thrilled and delighted. The new caps just went into the crossovers. I attempted to A/B the old and new. The difference was striking right away. I’m sure they also require some break-ins. Whether or not I’ll be able to recognize the subtle improvements over time is totally subject. Once again, all I can say is that I couldn’t be happier with my overall experience with Pure Audio Project.
