I must say that neither I or Marty could explain what we heard but there was no question that the gain was increased 4-6 Db with the Typhons in the system
Steve,
2-3 dB changes of subjective preferred level when you change amplifiers and sources is usual an has been referred by people such as Ralph Karsten of Atmasphere and was often referred in the tube versus SS debates.

Steve,
Technical oriented people definition of gain is incompatible with your free use of the word. Gain means Vout/Vin - this does mean just the opposite you are writing. When you used the Typhons you used a lower gain setting. Am I correct?

Of course - to offset the gain increase resulting from inserting the Typhon....

Yes, but in is this case it is "perceptive gain" something that can not be measured with instruments. You need to carry experiments with people to establish it.
It is totally plausible because when I inserted an all Transparent system, my gain was attenuated by 3-4dB!

(...) The typhon must somehow result in higher output voltage on the poweramp for the same input voltage, be reducing a bottleneck in power delivery to the amp.
Different scenario. You insert a filter into the signal path. (...)
Sorry, but IMHO this is physically impossible in any decent power amplifier. If the amplifier gain would depend significantly on the supply voltage you would be listening to your mains, not to music! It is why power supply rejection ratio should be very high in power amplifiers.
so Francisco are you implying my measurements are wrong and that what Marty and I heard was a figment of our imagination
Whether there is a sizable (4dB?) increase in power output at all frequencies for the same preamp gain should be easily measurable with test tones. But whether you actually heard increase in dynamic headroom - which you can also measure, but this time playing music - is another thing, and I have a feeling this is what your testing will show.
