THE major reason I have not bought any of Fractal's cab packs is the lack of Wave audio format IR's (.wav). With a .wav file, you can convert it to be compatible with lots of things. Also, you're not limited to only Fractal's Cab Lab plugin. I own MixIR2 and paid good money for it a long time ago. It still does the job, easy to use and is great quality. With .wav files you can use whatever IR loader you want. I feel like Fractal is pulling the old "Apple" proprietary scheme with us. This is why I solely use OwnHammer IR's (and because they're freaking awesome). The day that Fractal starts to release IR's in .wav format, is the day that I will consider buying from them. Until then, I'm content with OwnHammer.
