Oh it definitely happened. And not only did they downgrade the internals and continue to call the SS amp the same model but, their tech line is telling people there are no difference when obviously there is.
As if that wasn't enough, now the PPI Phantom series (same internally as the original SS TN series) has been discontinued.
So, exactly what is going on with Epsilon? IMO, several things possibly. 1.They are just basically transitioning over to Boss/Pyramid quality level stuff in order to make as much $$$ from the names as possible before gutting/selling/closing the brands down. 2. The company is in deep financial trouble and are cutting overhead costs by reducing quality in a effort to create wider margins. 3. They're just idiots who didn't think anyone would notice the old 'bait & switch'.
Of course, a combination of all 3 scenarios is also possible. This is Epsilon we are talking about!
