If money is no object, Separates rock. However, I used to run separates, one preamp and two amps, and found that all of the interconnects add up. I switched to a McIntosh MA 12000 and since I only needed one interconnect from my Lumin T2 streamer, I was able to go with AQ Dragons.
My dealer wants me to go with the new HiFi Rose streamer and still to come out, power supply for it, But I am curious about the 432 Evo.
