how do i know that i will be purchasing a newer version; the following quote was taken from an early post from a user who said he emailed sebatron and this was their reply "The upgraded units feature more gain and refinements. Bottom end response has been tailored . In other words we shaved half a db or so around 120 hz.There’s also an improvement up top around 12khz. The old 2000e review isn’t about the new one….the one that we build now.’ ion".are these older versions still out there????????
