I am using a Preeminance 1A passive ahead of Atma-sphere M-60 II.3 with the best results in my system to my ears thus far. The actives I have used (Cary, Sonic Frontiers, BottleHead, Musical Fidelity) imparted a color to the sound peculiar to each preamp that I only noticed due to the tranparency of the passive.
I would equate it to prefering water to drink over soda. Water is quenching and ulimately satisfying where as soda is great at first but leaves you with a thirst and an after taste that may not be pleasant.
