Hi,\nand thank you for your time. Bought a sony 75xbr940D so i can see 4k, have xbox one x, but old arcam avr350 that cant pass the 4k so need to upgrade and thinking separates vs. another AVR that i will have to replace in a few years. I have Vandersteens all around: 2ce signature II fronts, vcc5 for center, vcc2 for the two sides. I've been told these are relatively inefficient speakers & need power for great sound. the local shop, which i like, threw out a few options include NAD due to the ability to add modules as tech changes. I'm thinking i would like to spend my limited budget on a quality amp that i could keep for a long time (doubt i will ever upgrade beyond the 5.1 set up) and less so ($) on the processor. That said, i would appreciate hearing what smarter people than me think. any help is appreciated. i suspect my budget for the amp is <$5k but i am OK with used equipment.
