Saying that all ARC amps are not musical is a statement that is untrue and one that thousands of ARC owners would refute. The HCA-2 is NOT better than a VT-100 Mk II. I had both & ended up keeping the VT-100. The VT-100 sounds more like music than the HCA-2. Haven't heard the Zeus, but most people who have praise it, and Rogue has done a pretty good job with their other products, such as the 99 preamp.
