I arranged a purchase of Snappers for a friend with Dunlavy SCIII's. I got a "family" discount but my brother don't work there no more so don't ask. They did spend a brief time in my system but I also got to hear them several times later.
Aptly named but they don't sound like SS. They retain an "organic" tube quality but without getting overly lush in the mids. With the Dunlavy's, it was a well balanced combination and the Snappers complimented those speakers ability with leading edges. He particularly liked the grainless highs. My speakers are much more demanding and the Snappers didn't have quite enough oomph, similar to the Monarchy SE100's (SS) in that way. A Plinius SA100 was my solution and compromise. Even with the Dunlavys, which are not an efficient design, they didn't have the bass of his previous Coda System 100, but that was expected. The Coda, like the Plinius, is a heavy brute. He preferred the Snappers but he only listened sporadically and spontaneously so warming it up became a hassle and leaving it on was like watching the tubes decay.
Forward? More so than the previously mentioned SS amps, which I would tend to call "laid back" but stable and not aggressive.
Small jazz? Don't know, I prefer a big jazz.
Overall, I preferred the Snappers to competition like the Jolida and ASL by a wide margin. The Rogue M-150 and VTL MB125's are closer rivals but don't have the looks. The Snappers are unique in their class by both being fully differential and ultralinear.
