to me the 4040's kinda vanilla no matter what you plug it into, IMHO and all that crap.
never used a v69
(my sytek has the bb on all 4 chan)
as for the sytek, i can actually tell the difference form my mixes before and after i got it.
before my best pre being an rnp and using it on as many tracks as possible
and now sytek being the best one i own and useing it on as many tracks as i can (think buildup)
my stuff actually sounds a little better then before.
go figure.
still occasionally choose the rnp over the sytek, and the di on the rnp is the shiznit. and the sytek has no di anywho.
IMHO and all that.
