Yes I use the quark in my 127mm in SS mode. When I want a more narrow bandpass I add the DSII unit and use the scope in double stack mode.
The quark I have gives superb prominence views and reasonable surface details. It is the prominence version. You can also get the chromosphere version with narrower bandpass and more surface details. This is the one most people get. I wanted the wider bandpass to observe faint prominences.
Quarks are a great when you get a good one. In the solar imaging community there are many stories of people sending back units because they disappoint. I had the same experience. I suspect those who do imaging will be more fussy than those who do visual.
The Quark is a great idea and turns any refractor up to 120mm into a solar scope. You do have to add a UV/IR blocker to reduce the heat load on the quark when operating with 120mm aperture.
