Why do people release new EQs and gizmos? People like to have tweaks. I have a pile of 932's - I certainly won't be changing any of them because some R7D fella has tweaked a new curve that might sound great on whatever it was tested on.Do you really think people using a system twenty years ago had the 'wrong' curve? No - they had the popular one for that period - just like the smiley face of the 70s. The key point in this topic was we were talking about Peavey, not a Versus. You've totally and utterly missed the point. If you work on top end systems and know the R&D guys home phone, you can get the latest updates - chasing updates for firmware, software and adjustments seems to be the modern way to guarantee optimum - yet in the end, it's a personal choice to make something better (as in, different, not better).
Vertec being on revision 5 means one of two things. Their earlier ones were poor (I don't think they were) and the later ones are wonderful (but probably just flavour of the month different)
You carry on with your system tech conversations it will keep you happy. Those tunings you are now unhappy with, are because you like constant updates. Clearly you can hear the difference and like it. Which means your system was poorer before - when you also liked it? Don't confuse the core elements of this topic with your mega tweaking addiction. It's perfectly fine for top end guys like you to pursue excellence if it's dangled before you. That's why you get paid big bucks and are well respected in the industry. The trouble is we also have people with some boxes in a small pile or on a stick who want to make them better. Bi-amping a Peavey with a switch and a soldering iron is a great thing to try to give you more scope for adjusting what comes out to the best you can get it. This is great experimentation. Oddly, very like your top end systems, the results are small tweaks really, not huge differences. The constant twiddling on a budget product just isn't going to happen. On a system where a new driver costs the same as a new PA, tweaks are somewhat more, er, modest in success.
I've no idea why you moved from bi-amping a Peavey through VRX to Vertec. What are we talking five grand a box? You also muddied the waters with the mention of the tunings for the 932LA - this kind of tuning is really just a curve adjustment, and I suspect just a way to tweak further the response when you've used the lo vs hi adjustments as you add more to the curve. My experience is that really bi-amping these boxes is a bit pointless because in normal mode the -3 or +3 switches balance the distant sound more simply and predictably than doing it with two amp lo-hi balance. Each to his own of course.
