Yes I as well have used Vishay S102's many years ago and ran an ear opening experiment with them. I had an Adcom 535 Amp. De soldered one entire channel only with about 13 Vishays Bulk Metal Films. The ones that cost about $10.00 Each. I did this just for one channel only to see if I could hear the difference, and let the other channel alone.
All I can say was WOW WOW WOW.The noise floor dropped way way down. You coud hear absolute silence between every note that was played thru my phono stage. Detail was magnified substantially But without any hardness to speak of. Everything was absolutely effortlessly in reproduction. Once I installed the ther channel the 3D imaging really expanded wall to wall. To bad I still do not have that amp today. It was one of a kind and alot of work, But worth the challenge. I hope this answers some of your questions.
