I can't tell if you're serious or not, but this actually happened to me twice. Miss Willis first threw up on my Pioneer DVD/Laser. Cat voimit is highly corrosive and it destroyed a circuit board. I took it back to the dealer, explain what happened and they fix it at no charge. Being a regular buying customer does have its occassional benefits. The second incident was 18 months later and Miss Willis voimitted on a Sony ES power amp. Again circuit boards were ruined. I returned the unit to Sony and they refused to honor their warranty citing owner abuse.
Since in each case the throwed up over unit stopped working, I can only comment that cat voimit as a tweak does produce blacker blacks and improved intertransient silence, YMMV.
My serious advice is to immediately have your unit professionally serviced.
