Sirspeedy, I've posted numerous times here about SST because I have the same "over the top" reaction to it as these "over the top" rave reviews of which you're skeptical. In my system, Walker Audio Extreme SST makes a clearly and significantly positive sonic improvement. The same is true for two other members of our local audio group who have experimented with it, and we have several more who now have it to try so perhaps they will chime in at some point since they also post on Audiogon. In my opinion, the only question is whether the improvement is worth the cost "to you." For me, it makes such a material difference that it is WELL worth the cost.
Jes45, the caution about how one uses SST or any contact enhancer is well taken. And, I've been using it on all of my tube pins with no mishaps, just like
Arthur Salvatore, just like
Srajan Ebaen, just like
David Robinson, just like
Bill Gaw, just like
Lloyd Walker in his personal system. And I've talked with Lloyd Walker who says (as of three weeks ago, prior to CES) that he's received
zero reports of any users having a negative experience using it on their tube pins. Still, it is important to follow the instructions and use it SPARINGLY.
