I am building a 6 channel amp for my MTM biamped speakers (one amp per driver). I have researched all the possibilities for power transformers (toroidal) and realized that it would be much more economical to buy one very large transformer (1000-1500VA) and just run all the amps off of one. My power requirements are relativly low, 20w of class A /channel that consume about 100W. I want to know if I can run multiple amps off of one transformer, or if 6 smaller discrete transformers would sound better, or maybe 3 or 2 or any other combo. Thank you for responding!
