Good price on the CA2A, but still only getting the VST version for $15? I guess it's worth it to use elsewhere outside of Sonar. I demo'ed the CA2A and liked it.
On a side note, I did just snatch up the PC Concrete Limiter while on sale and applied my store credit. Total cost? $15! I've heard much praise about the PCCL and I look forward to using it. After all, I don't have a good and effective limiter in my arsenal besides Boost11 or LoudMax-64, which are both just OK.
