My instrument is an 1820 Panormo. I have experimented with medium to heavy gut strings for about a year; with Pirastro Olives; with Passione; with Pirastro Gold, Evah Pirazzi, etc. In terms of heavy to lighter strings, I have always found the Evah Pirazzi too heavy. If you want to pound the instrument with concentrated force, as many soloists do these days, and never play softer than a MF, I guess they are good strings.
But of all these strings listed above, I have found the Peter Infeld strings to be the best combination of: quality of sound first and foremost, projection and power, overtones, and string ring. You can always find a violin or bow that does one or two things well, but to find the best compromise of many qualities desired... it is difficult. In terms of the most qualities I can find in one kind of string... Peter Infeld is it.
