Hey grannyring,
One more point I forgot to share is that it makes prefect sense to me way you can drive your AZ's without a tube in sight, and get the beauty you want in your system. The Crescendo's are slightly warm and full, therefore, the synergy you get with a more detailed/transparent upstream set of gear is a great balance. You "seasoned" to get what you wanted out of your system like a great chief uses different flavors to get the meal to taste the way they want.
