I have not heard the Lamm although I do have an Io sig with volume controls and I recently added a 2nd power supply.
Taken all in I agree with most of the comments made.Just wanted to point out that the Io has been flawless in reliability to date.It is however a late production model. I have selected low noise telefunkens up front and the system is very quiet running direct with a Benz Ruby or Helikon. This is a function of your overall system sensitivity.
The Lamm may be quieter yet not as much gain or flexible in loading. Choices, choices...
