In so much as people's hearing differs--Their likes and dislikes--Their experience as listners differs--The rest of their equipment and the room--the amount of care in set-up,all differ. I doubt it would that difficult to substitute a class B product, within a given system, and get better sound than it had with the class A product it replaced.
++++StereoPhile Class A components+++++
Any of you guys who have listened to more components than I have, or maybe anyone who has been in the industry: I see a lot of posts mentioning "stereophile class A " etc, so I assume this recommendation carries a lot of weight. (After purchasing my Audio PHysic Virgo II's, I saw that they were class A in stereophile, so I felt like I agreed with what they were saying.) Are the reviews completely independent? With the vast array of components out there, can they really cover all of them? Do you guys really agree with the class A and B thing? Thanks for the perspective....Mark
