I'm finding that power factor correction even though an audio system is on the small scale of things, makes a difference.

Even just using the .1 uF caps that are UL approved makes a difference. I initially though it merely shunting off noise, but I was informed by an EE that according to his measurements, it as affecting PF to a certain degree.

One of the things I have noticed is that running the snubbing circuits after the diodes, while making a sonic difference, ignores the spikes reflected back into the power transformer secondaries.

Since I use tubes, it is difficult to shunt the the B+ leads directly. Pondering the the reflection concept, I snubbed the other secondary outputs, namely the filaments. I was greatly rewarded by a much smoother and fuller sound. I was rather shocked at the amount of change and started to look at power transformers very differently.

Of course YMMV and FWIW
