Looking for advice on a 3 channel Hypex Ncore amplifier - ATI vs Nord\/Apollon\n\nI currently have a ATI AT528NC amplifier which powers my surrounds and atmos speakers. I am looking for another amp for my LCR (Procella P8). I have decided to stay with a Class D amp specifically Hypex ncore based.\n\nI was wondering why there was such a discrepancy in weight between ATI (17.8 Kg) and Nord's (5.6Kg) implementation of hypex ncore and if it impacts the performance in any way. It seems that ATI uses a linear power supply whereas Nord and Apollon use SMPS. ATI offers a much better warranty and has very good reputation but I am not sure if the price difference is worth it.\n\nLooking into ATI AT543NC vs Nord One NC500DM\/Nord One NC500DM MKII or even cheaper Nord One MP NC502 \n\nOn the AVS forum there are backers on both side and I was wondering what do people on this forum think. I know there are several members here who are much more knowledgeable than me when it comes to these things. My goal is to buy an amp that I would not need to upgrade in future (unless it dies on me) even if I change speakers.
