I have the CA-14 cards and CA-Ugly pre-amp, have been extremely happy with the setup and have had no problems stealthing. In the past I've owned both the SP-CMC-8s and DPA 4061s. I think the CA-14s sound much better than the soundpros did and while the DPAs are better mics, I definitely don't miss all of the surrounding chatter/noise they picked up nor do I miss having to EQ the excess bass. For the low price point (paid $225 new for the mics and Ugly), I don't think you can beat the quality.
If you do go with the CA mics, just be prepared to wait a while if you order them new. When I bought mine last year I was told the build time would be 5 weeks and it took almost twice that long. I also wouldn't call customer service a strong point, but in the end it's easy to overlook due to the quality of the product. Just my .02.
