Point to point wiring is absolutely necessary for designers who cannot design a decent circuit board. I was lucky. My designer was a NASA rocket scientist who helped with both the moon landing (Apollo 5) and Voyager missions. His circuit boards did not have "Thin" Crap. Too many individual wires means too much noise.
Point to Point vs Circuit Board
I just read this about point to point wiring:
First, there’s the music’s signal. You spend a lot of money on interconnects. So why have the signal go right from the RCA jacks or speaker terminals into circuit boards with copper traces so thin you can hardly see them? What’s high-end about that?
I've now heard about point to point wiring in the case of tube amp companies (Jadis, PrimaLuna) and my question is does point to point wiring exist for solid state amps? When I look at images inside amps online all solid state amps seem to use circuit boards. Is there such thing as a point to point transistor amp or must they necessarily have circuit boards? If so, which companies?
Thanks

Six of one, half a dozen of the other. If the circuit board traces are thick there will be less resistance in the trace and therefore will not be energy thermal loss. Depending on design either can have capacitive and inductive reactances that can affect sound quality. Design is everything. In tube amps having independant tube mounts that are bolted to a frame are much better than epoxy mounted soldered tube mounts. Epoxy boards over time get brittle by the high heat tubes radiate. Solder joints can loosen on the board as well. Point to point wiring normally will carry more current and have less loss. With solid state production costs and assembly labor would be enormous and difficult because usually has many small components. Servicing point to point solid state would also be difficult. Can you imagine the mess of a home theater reciever with point to point? If well done printed definately best for solid state. |
Blue circle amps were all point to point... http://www.soundstagenetwork.com/revequip/bluecircle_bc208.htm |
