Cranborne Audio Camden 500 - Pretpojačalo
The Very Best Of Both Worlds
Camden 500 is the most astoundingly clean, linear, transparent preamp you’ve ever heard. But it also has “Mojo” - 2 discrete custom analogue saturation circuits that can be applied, exaggerated, and perhaps best of all - bypassed.
