Kaplan KA310-4/4H Amo Violin Heavy

The Kaplan Amo strings I have ordered in "heavy tension", to balance with an Istrument from the early 18th century with very high ceiling vault (previously with Pirastro Evah Pirazzi gold medium strings) the sound properties. The instrument was lacking in depth and overall the sound was too bright for me.
After a short lead time, I am now very satisfied. The low frequency components have increased. Overall, the sound has become fuller and more powerful, and the "lagging time" of the strings is even longer than the Evah Pirazzi strings!
Only the speech has become somewhat worse.

The D-string had a small "Macke": outside adhered some kind of plastic. However, only so little that I only after a short time at all. Since the spin is under order and sounds in the sound seems to be correct, I keep the string anyway and give 4 stars in the processing.
