Some folks here are understanding “noise” incorrectly. We are not talking about the hiss, buzz, hum etc…coming out of your speakers as you turn the volume up with no music playing. The Puritan 136 & 156 help remove noise that is actually in the final audio signal - the music you hear. This noise can be defined as any unwanted signal which is corrupting/perverting the fidelity of the recording. These artifacts can blur, add haze, distort, corrupt tone, constrict, mask and obscure detail and on and on….
My mention of the DC blocker in the 156 is referring to the buzz/hum that transformers can make as they vibrate inside a chassis. Residual amounts of DC riding on the AC line can cause some torriods to hum and vibrate. This phenomenon has nothing to do with signal noise.
