Hi Steve, it looks like you admire Proac a lot. So you may look for Studio 140 as you mentioned. But I will look for version Studio 140mk2 which is improved. Or a new Proac DT8 which is easy to drive look stunning and price is still very good. Quad 22L2 is not in the league od those hi quality Proac or Ruark speakers. And they do not like loud volumes at all. Ruark here is a legend with probably best build quality, high quality components like their top Dynaudio midrange driver. But sound is I thing better at Proac. Proac is more lively, faster, has better sound projection. It is also reason why many good Proac speakers sound great with tube amplification. So you have something to think about. I am also a big fan of Proac even I do not use them. BR.
