OP…you have some great thoughts and excellent equipment.
I agree with Lewm. Why should we box ourselves into a corner whenever we are trying to decide cost performance ratio and expenditures for our equipment. I don’t buy into that “you should only spend X amount for this equipment when the other equipment costs X mount”. Now, of course, the rationale for expenditures is a personal matter depending on individual situations, budgets, synergy, etc.
All I can say, is why can’t we embrace modding our systems the same we mod our muscle or sports cars? No one ever says well, you should spend X amount for exhaust, titanium for example, or headers, air intakes, carbon fiber, wheels, tires, etc.
In the end, it’s about delivery and execution and one’s own personal satisfaction. When rolling into a cars and coffee with new carbon brakes and wheels on older sports car, people are more apt to say “wow, wool”, and so I think it should be the same with the audio hobby. Test limits or think outside the box to satisfy your our interests. Have fun and enjoy the musical roller coaster.
