I plan on getting a 64GB Touch after I get my customs, then an amp for the LOD, then after that I'll see if my ears are still wanting more and try out the CLAS (perhaps at a meet if possible). There's nothing stopping you from returning if you don't like it, distance selling regulations and all that (at least over here).
BTW, I AB'ed my mum's Touch 4G vs. my about to be sold 3GS (4S incoming) today and they didn't sound identical, so it'll be interesting to compare the 4S when I get it, although I don't plan on using it for audio. One thing I did notice straight away with the Touch and 3GS was that the latter had some pretty obvious bass roll-off; I always use the subwoofer test track Woofer Cooker which has this ridiculous frequency sweep at the start that goes down to about 20hz and maintains a constant rumble. The 3GS was barely audible while the Touch kept it together all the way to the bottom. The overall sig felt a little different too, although I did this while updating her Touch to iOS 5 and her laptop to iTunes 10.5 so didn't listen for more than 5mins.
