As the Pirastro catalogue describes these strings:"The power string* very intensive and powerful* brilliant and complex sound* widest dynamic range* emphasize the individual sound pictureof each instrument* outstanding response* immediately playable* perfect set harmony* resistant to changes in temperatureand

great set of strings with dark and powerful sound

Excellent set of strings!

but I like not having to break the set, the Evah A I actually prefer to the Larson

I'd definitely recommend them to anyone looking for a solid set of strings!

I tried to save a few bucks and get a less expensive set and was so disappointed that I turned around and went right back to these.
