Post Subject: Floating RipplesPosted by hagtech on: 12/25/2007
the subject of the intermediation is kind of complex

It's difficult for me to guess exactly what the possible sonic effects of the ripples would be.  I see a tube operating at a fixed point, having a particular distortion spectrum.  Say -42dB 2nd harmonic.  Then, the ripple pushes it to a new operating point, giving -40dB 2nd harmonic.  So the treble signal is modulated where distortion fingerprint changes at a 120Hz rate.  Is that audible?  What does it sound like?  Maybe I am chasing ghosts.

Similarly, we have the same thing with DHT, as the operating point of tube changes with the temperature of the cathode, heating and cooling at 60Hz. 

Maybe this is so far down in the noise floor we cannot hear it yet.  There are other peels to the onion that must be removed first.
