Thanks all, this has been super helpful. I may be able to get listening in my house, but I have not asked. I think that gets easier if I own the speakers first. I still want to heat the CJ 120. Not sure if anyone has heard that pairing as well?
Right now, I am running bookshelf Electra Amriors with an MC275 and a C22. The speakers are what I want to replace, but I am confident I need to replace the C22 if not the MC275. OF course, I do not want to do this all at once, so I am trying to figure out what I can keep for now. My guess is If I end up going to ARC route, I could find a used ARC LS28SE keep the MC275, and get the Serifinos. Then over time move to a new amp and also decide if the pre is good enough. The C22 is cloudy and not very good with the Serifinos.
