Doesn't sound cocky, just kind of dumb considering you can get the same preamp circuitry with as good if not better build quality and features for the same if not cheaper.
I've heard the real one and the BAE and can't tell a damn difference (U87 side by side). As far as I can tell it's not worth the extra money for the original parts and full of lead solder.
As far as I can tell Brent Avril nails it as close as they legally can. I have never heard any of the Vintech stuff but I'm sure it's also good.
