I haven't seen any conclusive data that moving from Behringer
to other products will guarantee an improvement in sound.

When you spend more money on any audio upgrades, from any
manufacturer, it always sounds better, .... lol .....

There are really good Behringer products and not so good products,
judge the specific product not the brand name. Some of their
electronics have a proven track record on sounding neutral, but
you will get people to disagree... lol

If you look at some of the Rane product, they may use the same
opamps as the Behringer product, yet the brand naming placebo
effect causes people to like Rane better, lol.

I've notice in the DIY electronics world, even a neutral sounding
Behringer product generates excitement from the mod community as
they look at the schematics and feel the strong desire to modify it
to improve the sound. What do you think happens after they mod
the gear ? Of course their mod is way better in sound, everyone
who designs their owns electronics will claim their design is
leaps above any other design, lol ......

Conclusion. Identify a sonic problem first, then try to fix it.
If the fix is to replace the unit, then try a different brand. Don't
fix it if it ain't broke.
