First time of venturing into tubes and i'm a little confused on impedance matching, the pre amp is a Prima Luna Evo 100 with an output of 2800 ohms and the amp is a Nad 220 that I just had recapped with an input of 25Kohm It seems like it might not be the best match, which is why I'm putting this out to you folks that have far more knowledge, and I would like to know better before purchasing the preamp.
I agree with George, it’s borderline. Under normal conditions it shouldn’t be a problem, but during peaks and transients, there might be noticeably weak bass.
