Outdated because new features come out fast, but future proofing is almost impossible with an AVR or Pre. AVR generally easier to replace than a Pre. My new one hasn't even shipped yet and they are already releasing the new HDMI 2.1 spec lol.
I use analog for music so pre or AVR matters significantly less, but I tend to prefer a simpler system for music only, though now I tend to listen to my main rig more for music.
I think this updating is a load of bunk now. 2K and the lossless codecs is all you need. I think you can aim to buy good gear and intend to keep it for the long haul.
In my main system I still have my Marantz 8003. The audio is fantastic in its realism. Sure it only had 4 HDMI inputs, but the Geffen switcher on one input gives me 6 for minimal inconvenience.
My 2K Panny Plasma gives a better picture than any 4K I have seen. My front row seats are at 12ft, so I would get zero benefit from 4K anyway.
The search for more features and streaming also makes no sense. You can easily add all the features you want upstream and add devices as program sources change and become available. I would never consider streaming from an AVR, pre/pro or TV any way. TVs, AVRs and pre/pros need to have design and materials go to core functions and not add ons and distractions.
My pre/pro still has excellent core functions and my power amps are real work horses. I have never used the smart functions of my TVs and never will. TVs just need to be set up and then just watched and all you need to benefit form it core functions is the on/off button.
I think this Atmos business is also absurd. Any sub par speaker added is a detriment. In the home there is no way you will set up that number of high quality speakers. I firmly believe all speakers need to be of comparable quality especially across the mid band or you focus on the odd man or men out like a laser beam.
Once a technology is reasonably mature I think the best advice is to buy for quality and longevity. Most of this push to upgrade is hype.
I think from the rumblings coming on now, upgrading to 4K and higher versions of HDMI is buying people trouble. The HDCP codes are much more complex and draconian now and the handshake rate is much higher. I note the new HDMI boards are now twice or more the cost of the old ones. This means more processing and more heat. Inside a receiver with amps, that means more failure is highly likely.
I have absolutely no intention of upgrading unless there is terminal failure of a unit. My picture quality is excellent and the sound absolutely of the highest order, with excellent 360 imaging from the 7.1 system.
Bottom line advice is to build the best highest quality system you can and be happy with it for the long term. That is cost effective and gives the maximum satisfaction.
