Over the years I have tried many different strings on my Alhambra guitar. It came with D'Addario Pro-Art'e. They were fine but I wanted a different tone, so I tried many others before settling down with La Bella 900 Golden Superior. Yesterday I opened the case to find I had a broken string. I ever change one string. I always change the set. I had 7 different brands of strings, so there was not a problem. As I looked through the strings I found one brand, Stahed in the back, that I had never tried.
( Thomastik-Infeld Classical Guitar Nylon/Silverplated Chrome Steel Flat Wound Light, .027 - .045, CF128 ) It gave my guitar a totally different tone that I found much more pleasing than the La Bellas. I will play them for awhile to see if I still like them a week from now. but I think I may have to stock up on a few sets.
