Viridian, this whole "A" "B" "C" thing is foolishness if you can not afford Class "A".
I spent years subscribing to "Stereophile" and spending time in high end salons. After reading "Recommended components" I went and compared the "sound" of the component" and other components in that class; you will not get class "B" sound for Class "C" money. Now there are many different sounds in all the classes, and for that reason you might prefer a class "C" component over a class "B" component.
I just ordered a cartridge that's class "B", but costs more than another similar cartridge that's also Class "B". I'm not buying these components because they're Class "B"; I'm buying them because they sound good. If I could afford Class "A", I would buy Class "A"; not because it's "Class "A" but because of the spectacular sonics. If I could get Class "A" sound for Class "C" money, I would buy it all.
One of the best examples I can think of at the moment is "ARC" and Conrad Johnson; two different sounds when both are class "A".
Compare CJ PV12, and CJ PV10; both are CJ but PV12 sounds better; while both sound good, one costs more than the other although they both make Class "B"; that means buy the one you can afford, but money is the boss denominator. Many people have them both is why I gave that example. In the end, I'm not buying class "B", I'm buying Class "B" sound; if it was free and delivered that sound, I would really go for that.
I don't get the connection between a "synergistic" system and the different classes of sound?
