i have been using Micca RB42 on my desk with yamaha rn602 for about a year and pretty happy with the way they sound for desktop use. I am looking to upgrade to better speakers now with budget ~50k (+/- some). I like the way the RB42s sound (without having to use bass/treble controls. I used to drive these with a Topping PA3 earlier and was still happy with the sound. Now i have more space to accommodate bigger speakers, not floorstanding though, still bookshelf and with similar 'sound'. 90% usage is music at low volumes and it pretty much plays throughout the day (unless i have attend a meeting). i am planning to audition Qacoustics 3030i and KEF Q350 in a day or two. was just wondering if anyone here has used RB42 and can comment on if i am looking at the right speakers or should i be adding others to check. thanks!
