Greetings AC'ers. I am in search of a high quality DPDT toggle switch that won't be detrimental to the signal.
 Among other things, I want a better quality switch for triode/pentode switching on various tube amps.

 I know Percy Audio has some decent pieces but looking for any other options to consider.

 Thanks in advance for your suggestions.

I like NKK switches and have used them for power and in comparative situations, don't know if'n they'll meet your criteria though... NKK/Mouser
