Hello everyone! I managed to pick up a brand new, boxed (sealed) Pioneer SC-LX73 & BDP-LX54 today from someone locally for £450! The guy had bought them new in 2011, but ended up moving abroad for work and never got around to installing them. I used to own a Pioneer VSX-2021 a few years back and I stupidly sold it to purchase a 4K compatible amp to go with my new 4K TV. I had ended up purchasing a Sony STR-DN1040 and I have since missed my old Pioneer amp, until I found this deal today. Do you guys think that I grabbed a good deal today? Would you say that the SC-LX73 out performs my existing Sony STR-DN1040? I decided to purchase this amp today because I feel somewhat disappointed with Pioneer's current offerings and I could never find a newer model that I like. I feel that the audio quality of a high-end Pioneer amp will be equivalent to the SC-LX73 amp that I picked up today, minus some features e.g. Dolby Atmos and 4K/HDR pass-through, which leads to my next question. Which is the best way for me to get pure Dolby TrueHD/Uncompressed audio from my 4K devices? Should I: Run a HDMI cable from the 4K source to the TV and have the amp use ARC to retrieve the audio from the TV? OR Use a HDMI splitter to split the 4K source into two outputs. One will feed directly to the 4K TV, and the other directly to the amp? I'd really appreciate any input Thanks!
