The information I was able to squeeze out of Steve (Dillion) was that all of the Mark II sounds were originally recorded in 24 bit, just waiting on the Fury to come to the market. I know sometimes you have to put the cart before the horse, but at least Foxpro did the recording knowing that they were eventually going to release a unit capable of 24 bit audio.
I will be the first one to tell you that a difference can be heard between the 16 bit and 24 bit foxpro sounds. Now, this could be many things, including equipment used to record, the microphones, the dubbing, the background, the sound type, etc. However, to me, the Mark II stuff is cleaner, more pure sound. I would think that this is a better microphone, done in a more sound friendly environment, with better recording equipment. That is a trained ear speaking...but like I said, it could be variables of these things.
Now, I am also one of the first to tell you that I am inpressed by SOME of the WT sounds. I am also impressed by most of the JS sounds. What does that mean? Well, I want a 24 bit calling unit with a good speaker setup. I want one that I can load various sounds on at my descretion. I think that the new unit from Foxpro is the unit to have, at least for the time being.
