I was wondering if all the newer WT 800 are a B series. Mine was destroyed and replaced it with an iAMP 800. Not that its a bad amp just not my cup of tea. Mine was an old wt 800. 1995. Are the newer ones as good as the old. Has anyone compared the older with the newer WT's? I would like to sell the iAmp and get another Eden WT 800. But Im not sure if the newer one's are as good.
