Hi
I'm new here. I have recently built my first DIY class D using two Icepower 125ASX2 in BTL modes (dual monoblocks). I'm using them with NAD C658 Preamp DAC (XLR) and a pair of Focal Aria 936 speakers. While I'm happy with the overall sound, I feel that I can do better.
I can get two Icepower 700AS1 modules for 700$. These are the same modules used by PS Audio Stellar 700M. But I'm also considering getting two DIY kits of the NC400.
According to the 700AS1 datasheet, it is based on a full-bridge topology, which means native support for balanced input. Other Hypex modules like the UcD700HG are based on a half-bridge topology, therefore they are natively single-ended amps. I've checked the NC400 datasheet, and it does not say if the NC400 is half or full-bridge topology. Also, I could not find any info about the optional HxR add-in modules. So here are my 3 questions:
1. What would be a better choice: Two Icepower 700AS1 or two Hypex NC400 kits?
2. Is the NC400 full or half-bridge topology?
3. What benefits does adding HxR cards to the NC400 have? What are the HxR modules? DC supply Regulators?
Thanks
