Based on the two annealers, the main difference appears to be the creators of the AMP system have put in a huge amount of research as to the exact amount of annealing time & temperature that is needed for each cartridge type, type of brass used (hardness, etc). They have done all the groundwork for brass by manufacturer and case size. The annealing times have been preset whereas with the EZ system, it's still up to the user to figure out how long to leave the cartridge exposed to the heat. In my mind if you are going to do that, might as well just continue to use a flame based system that most of us have been using for years as you're still "guessing" as to the proper amount of over or under annealing time and the amount of heat you are doing. With that in mind, I think the AMP system is superior. I have watched it in use (a close friend uses one) and have tried it & it is simply amazing as it turns out perfectly annealed brass with every case regardless of case size or brand. Normally I would be skeptical of the type of claims the creators of the AMP system have put forth (watch their videos) ie, all the underlying research as to brass brand, hardness testing, etc in order to determine the perfect final outcome of the annealing process but after trying it myself with several cartridge types, I'm convinced they got it pretty much right. Whether it was the 338 lapua or 6mm brass, the cases came out perfect every time and exactly the same, ie, consistency which is paramount for round after round of consistent ammo, consistent neck tension, consistent bullet release, consistent spring back and of course, brass life. They've done all the testing on the brass post annealing relative to again, hardness (or softness as the case may be). No guess work which is the part of annealing I have always felt left me with a big question mark in my mind. As far as the single feed system of the AMP, I don't see it as a detractor as its very fast and normally I anneal in small batches anyway. With the AMP system, u could do it while watching TV for that matter. The future to be auto feed system would just be a bonus if one wants to pop for the extra $. Either system is a serious dollar commitment so unless you simply have money to burn a shooter needs to be loading for several precision rifles to make it worthwhile in my mind. If you're annealing now, it certainly would make your life easier. More time shooting & less time in the load room, better brass, better hits on target, oh yeah! Besides, you can't discount the "cool factor", lol!
I am admittedly a gear queer, but in this case I think I have a practical reason for exploring these two. They seem to be the best induction units around right now. I do not currently anneal, but the discovery of the induction method was the nudge I needed to jump into the pool. I am currently processing ~4,500 rounds of 7.62, and 1,000 of 6mm. My shop is reasonably well set up for moderate to high volume loading. I do agree that the science behind the AMP is appealing.
