Current system after 25-years of buying, selling and upgrading.
I am waiting for an Ars Sonum 30 Watt integrated and I may replace the separates - looking for a simpler approach to audio - but I may not be able to let go of the CAT which is one of the best amplifiers in the world. We'll see. Happy for now, and may stop searching something different - at least for a while.
I have the 3A Sigs at home as well as my 5s. The 5s stay plugged in for a reason. Simply put, they are better top to bottom in every way. Yes, the 2WQ subs will get you most of the way there, but it's still not quite the same. The 5s are more transparent and have less of a sound of their own. Especially in the imaging. I suggest going to a dealer to listen to the differences.
