I've been very happy with my TV but time are a changing and i'm seriously thinking about an upgrade for the main TV. When i bought the TV from costco (back in 2009 i think) it was top of the range and i paid around £1,600 which was a few hundred cheaper than anywhere else at the time. Most of the viewing is HD from Virgin and Bluray films and box sets. I've just upgraded my Pi Kodi to Nvidia shield and now i have a 4k player i'm thinking i'd like to upgrade the rest of the system. Now there's no way on earth i can afford a top of the line OLED at 5-6k+ andi also need to factor in AVR and speakers (which need to be wife friendly) as the HT-IS1000 (which is surprisingly good if positioned correctly) is all in one and won't handle 3d or some of the newer audio standards. I'm wondering if i should start with upgrading the sound first before the TV to spread the outlay, with perhaps QA i7000 and an AVR which can handle 4k, HDR and 3D throughput but not sure where to start. Any recommendations for an amp to pair with the QA speakers? As for the TV i could stretch to the panasonic 65DX902B if the price drops a little but i'd like to have a 3D option as i have a number of discs in my collection which have 3D versions and would hate not to at least give it a go and have the choice.
