Have come from using Evah Pirazzi (greens) for over 15 years. The Peter Infeld aren't as powerful or bright under the ear, but offer a warmer, more nuanced/complex sound. They do take a day or so to settle down and for the full sound to develop, and I actually prefer the PI sound to EP greens. However, the EP Gold set is perhaps more impressive straight out of the box with a more sonorous lower end (D and G) without sacrificing volume or response. I would love to compare the PI with the EP Gold again.
On my violin, the platinum E is noticeably more powerful than the other three strings, but to my amazement still retains that bare steel E sweetness. It's still on the bright side, but not overly so. In comparison with other E strings, the Evah Pirazzi steel E is a little dull in the higher positions. The EP gold E has a rounder tone, but less sweet. The EP Gold steel E is has a rounder tone but lacks the same sweetness as the PI platinum E, and the Oliv gold E offers a rounder, more brilliant tone, but perhaps isn't as sweet. I think it's a real toss up between the Oliv E and the PI platinum E!
Lastly, tuning stability is good. Longevity - to be confirmed!
