If you like the sound of your CA-14 omnis, maybe you should just stick with them. All these things that other people consider an "upgrade" may not be better to your ears. I would kinda' suck to spend $1000 on some "better mics", then decide you like the sound of the CA14's better. I tried CK62's when I had them and they just weren't the ideal flavor for me, same with Nak omnis, and ADK SC-T Omnis. I did like the JZ BT201 omnis, but in the end I like the sound of AT853 omnis just about as well, and they are relatively cheap. ADK-TL omnis are nice, you just need a rugged setup.
One time I ran my JZ omnis for a "brew fest". One of those places where they give you a cup and you can walk to every vendor and say "fill 'er up" as many times as you want. I'd been running those omnis outside a lot lately, and loving it, so I did the same here. In the beginning the tape sounded great because nobody was paying attention to the band, everyone was off tapping kegs. 2 hours later, everyone was shit-faced and decided the best place to hang out and gab was under my mics. The point is, sometimes omnis are the right tool for the job, and sometimes they aren't. When they are, even reasonably cheap omnis will sound almost as good as high end ones. When they are wrong for the situation, it's better to run directional mics. I would love to drop $1k or $2k for a nice pair of Earthworks omnis, but I know I would only use them a few times a year, and even then they aren't going to sound "10 times better" than my AT853's.
