Hi All, I'm a Pioneer VSX-323 owner and recently upgraded to an LG 4K OLED. When I purchased the amp a few years ago it was advertised as having 4k passthrough and I thought great, I'm future proofed. After acquiring my TV however I discovered that 4k was not working through the amp for some reason.. I'm assuming this is because the VSX-323 possibly does not support HDMI 2.2? Anyway, I've done some looking around this morning and come across the VSX-531D for £200 which supports 4k/HDMI 2.2 so is a possibility, the only thing putting me off is this is the DAB version, which to me will be a useless feature and I'm sure the standard version has been on sale for lesss than £200 before, so I'd be paying extra for nothing. Another option is the Yamaha RXV383 which is the same price. What are your thoughts? Should I go for one of the above or is there a better entry level amp I could go for?
