Only real notable difference is the x2500 has a phono stage for a turntable. I opted for the x2400 when deciding. That was a few months ago however when the x2500 was just out and the x2400 was still in stock everywhere, so better deals. Got RS to beat Peter Tyson with a Q Acoustics 3050 cinema pack for £970. Phenomenal system for the money though I want to add Atmos speakers and second sub... What HiFi is a joke. They argue there's a difference in expensive HDMI cable image quality, if the manufacturer pays them enough!
I had the same on an Onkyo amp a few years ago. Faulty caps on the hdmi board. Got a mate who was a Dab hand at intricate soldering to replace them. Sold it on to a work colleague who is still using it now! I only buy my AV gear from richer sounds though now. Their 6yr supacare is gold standard warranty. Brilliant. Took a 2yr old Panasonic Blu-ray player with a faulty disc door back, they swapped it for newer current model that was multiregion and bundled with a 3 disc 3d blu ray pack.
Yeh I am disappointed that my PS4 Pros do not play 4K blu rays - total rip off imo.
v tempted - it has 'Change the display name for input source.' my Onkyo NR414 on lets me use the preset ones
I think I may actually give that a go on my “sofa” (y) 🏽
