Anyone heard anything about these? The top of the line Evo 400 has very similar specs to the Dialogue Premium HP (which I bought in December and love dearly). Hard to tell where the improvements/differences may lie. The webpages for these products borrow the descriptions from the Dialogue series basically wholesale. Only real difference I spot is they've apparently switched to DuRoch tinfoil capacitors, from SCR tinfoil capacitors. Oh, and looks like they've added an RCA tape out, too. Looks like they've also added a headphone jack to the model that replaces the Dialogue Premium (now called the Evo 300).
