This thread has real good stuff / discussion . It helps me understand the application of "Ratio" better now - there is more to it than simple 1:10 min. . Thanks Georgelofi , Mapman , Almarg .
impedance match of preamp and main amp.
I am considering mating a Mcintosh Mc602 with a Bat Vk 51se. I noticed the input impedance on the Mc602 is 10K. While most Bat amps are much higher. Does anyone see a problem with this? It seems I remember a Stereophile I used to know told me about a ratio minimum of 1 to 25. I am not sure though.
