Got the CA9 on Friday and did a quick rack job for the gig that night. Yes, it sticks out the back some, but I'm satisfied. I made up some rear supports on Saturday and it's tight and secure. I did manage to keep all the other rack components so all I really did was change the amp. It's heavy though. I weighed it on my bathroom scale at a whopping 72 lbs cords and all. That is a big diff from the 37 total when I had the PLX racked. BUT, I was impressed during the gig. My NV610 opened up like I never heard it before. I Horn Guys complained instantly.. I made a few tweaks because I didn't have time to play with it before the gig. All I did at home was plug it in and make sure everything was working. The tone was very thick and solid but tight. I only had my Demeter on 2.5 with the Crest in parallel mode, the channel one gain was all the way up which is how I always run my amps. One thing I definitely noticed was when I moved away from my rig to jam out with the Geetar Man, I was able to hear the rig with all the clarity and volume just like I was standing 3' in front of it where I'm usually at 95% of the time. I felt like I went from a V-6 to a high performance V-8. I was burning rubber! I've got another outside gig on Wed. and will give another report how if fairs at this much bigger venue with a way higher ceiling in this tent. This is a big stage with a big sound system in giant tent with open sides. Friday's gig was a very small tent with open sides so it's liable to sound quite different. This is the real deal test gig for me. I had a rough time last year with the HT322 and the PLX. Just couldn't hear my rig and had to get lots of monitor to get by. So, we will see.
