I have 4x N72 and 4x J99. The J99s are similar to the Hardy M1 (but the J99 uses a two-stage gain, versus the M1's single-stage gain). The only real difference in performance is the J99 will have a bit more gain for low output mics, and a bit more headroom.
Anyway, that said... Both pres sound fantastic. But when it comes to the nether regions of the frequency spectrum, the N72 comes up a bit shy; the J99 simply reaches lower. So, if you're looking for deep bass -- a thundering kick drum, a soul-rumbling bass guitar, or a pipe organ that will launch woofers, the J99 should be at the top of your list. If you're looking for some MOJO that comes from some harmonics, use the N72. Note that this is all subtle difference.
I haven't used the A12 or any API preamps yet. However, music I've heard recorded with them (Like "Wasting The Light" by Foo Fighters, recorded on an API console) seem to have an aggressive, gritty midrange that works fantastically for rock music. The N72 is more creamy and smooooooth in the mids, and the J99 is uncolored, but without sounding sterile.
I recorded a church choir backed by pipe organ. I had a stereo pair of DPA 2006As plugged in to my J99s set about halfway back in the room; a pair of CharterOak SA538B tube LDCs on the pipe organ, plugged into a Sebatron Axis 200VU; four Shure KSM-137 SDCs to close-mic the choir, plugged into my N72s; and a stereo pair of AT4047s on a piano, plugged into J99s. I got an immense rumble out of the pipe organ -- VERY solid low end. It turned out that most of that bass was coming from the DPA pair plugged into the J99s.
I just ordered four more J99s. When budget allows, I'll also order four more N72s. I love them both.
