I just acquired a pair of Prostat 922, recently re-mylared, Toroid II, and updated stators.
I’m coming from Quad 2905. So far, these have amazing midrange, the bass is more impactful, and definitely sound more realistic than the quads.
One of the bigger shocks is that moving the Quads to my office, they sound more impressive, more bass and feels more dynamic (a little more wilson like in harder hitting). The room is effectively smaller and i’m only 4 feet from the speakers.
I’ve moved from Quad ESL 2912 to Soundlab A3. I’m very happy with this evolution of my system. Soundlab are much better in every possible way. I’m looking now to upgrade my amplification. If some of you have Atma Sphere MA-1 for sale, keep me posted please.
