Spirocore Cello Tungsten C String

Concord has been my go to for years. They are remarkably fast, I have always gotten what I ordered and the prices are good. Many thanks for the years of service!

The most warm, resonant sounding C string I've played on. Prefer the tungsten spiral over Versum Solo and Larsen Magnacore. Can't go wrong!

I have been using these strings for many years. Have tried others but always come back to them. I play on a fine old Italian cello and the g and c tungstens provide a big beautiful deep velvet resonant sound. They are also fairly quick to respond and easy to play on. Sometimes it takes a long time (2 weeks) for the strings to break in, other times they sound great right away. I guess quality control is not absolute. They are by far the best strings I have found. Seem to last many months too.

Didn't have the freshness of a new string.
It didn't have power/volume/projection/edge Spirocore normally has.
