Kevin thanks for that informative reply. I hope I'm understanding it clearly. Here's few points I want make sure I'm interpreting correctly:
1. From what you wrote that its' difficult to tease apart the tonal effects of tying multiple pre-amp stages to single node partly because of how most amps are built and their poor grounding. Therefore direct comparison to the approach to filtering in the TUTs is difficult.
2. Better pre-amp filtering tends to sound better since it reduces inter-modulation. So London Power's approach to filtering (along with Galactic Grounding) every stage obviously solves all these inter-modulation woes and will sound better!
3. You get away with lower cap values if we use a proportional filtering approach ala the Standard in TUT5 but higher values are helpful if use the node approach like in the pre-am TUT3 Bassman and others?
Again thanks for your help. I can truly say Galactic Grounding and so much of the TUT info has been invaluable to me.
