Daddario strings, just brilliant.
These are not the cheapest strings out there but as is often the case you get what you pay for, they might beg twice they price but then they are twice the strings.
They sound great and they sound great for longer than the competition.
I find these do not change colour and feel dirty like so many cheaper strings, they stay bright for a long time and I have yet to break a single string.
I also find that they don't take a lot of stretching in when new, it's pretty much tune up and go.
I use these on a The Loar LM300, (also from Thomann though sadly now discontinued), the little Loar really sings with these, it's bright but very melodic, these strings really do make a vast contribution to the sound.
