(OP)
Can anything be done, having silver sodered piano wire, so that the wire will retain its` original properties? I have tried quenching in water but it did not seem to make much difference.

What are you attempting to do with the wire?

I loved the carbon steel wire business. You could work from one rod chemistry and by playing with heat treatment and draw combinations you could make 6 different products.

We used several wires that were hard soldered without additional heat treatment, but that was in the days of good old cadnium based solders and and brazing rods.

Rocket was made from higher carbon rod, and while the heat treatment was similar the tempering was different.
I don't recall the exact sequence of heat treatment and reductions.
I do recall testing it. You had to check the modulus, we used optical for extension. It was drawn so hard that you could screw up the modulus. You also had to take elongation from the crosshead movement of the tensile machine. The tensile samples never fit back together after fracture because so much material was missing. There was dust everwhere after a test.
