Switching between 2 amps , 1 set of speakers?


Hello all..if I wanted to switch between 2 amps to my 1 set of speakers guessing the best way is the manual labor way of connecting / disconnecting cables ....is there a switcher that doesn’t degrade audio quality or way to do this using connecting cables from 1 amp to another using some in/out safely? Thanks

Avoid switchers if at all possible. They are one of the cheapest ways to destroy sound quality.
@cytocycle thanks for pointing to Luxman. Looks like a well built product.

@douglas_schroeder is there no switch in the market that you feel is of sufficient quality?. When testing between amps, plugging and unplugging cables is quite a chore. If you think any switch will add color then I guess there is no choice. Very interested in your insight.
