butler, all Jadis pieces get silent updates from time to time that improve upon the original design. That would apply to JP80/JPS2 as well. We have used those preamplifiers in variety of full range systems playing heavy rock material with terrific results. Having said that, you might prefer the CAT for rock - it would give you more slam and macro dynamics that you mention In fact, it beats 99% of solid state and ALL tube preamps in that department. It is also cheaper then JPS2 by a cool 5K in line stage only version.
When you come to visit, you will have the opportunity to compare several preamps and make your own conclusions. If you wish to talk about it more, please do not hesitate to call me.
