Trigger warning for those who's insecurities and adorable child-like sensitivity to certain posts send them into rage or a coma: To save some money (although this would take some time) I suggest soldering every single cable contact point, including inside speakers, AC connections including wall sockets and component connections, power supplies, unsoldered or "clipped on" internal wires in everything, tube sockets, blue tooth dongles, and everything else (don't forget the phono cartridge connections)…then there's no expensive goo (although silver or some other "special real good audiophile" solder would help maintain tweaker cred in the face of other's thinking you'd lost your mind) and you should have no issues except mumbling jazz musicians sending sound bites to bounce off your magic hat rack, and possibly some tube swap delays...Get a "special" solder manufacturer to allow you to beta test their product, rave about it on this forum (don't forget to use the word "quantum" someplace), note the price and return policy while claiming no kickbacks from the seller, and let the fun begin. No break-in time, no goo, no problem.
