I happened to stumble upon this thread today and I’ve been absent from Audiogon forum for a while.
All the equipments you are looking at or are intending to purchase are great and it all comes down to system synergy and personal tastes or preferences. But I still think that the most important piece of equipment(s) will be the quality of your front end source components whether it’s analog front end source components eg turntable, tonearm, cartridge, phonostage pre or digital front end source component(s) eg CD/SACD player, streamer/DAC or streamer + DAC, etc. This is where the low level signal source starts. If you start or begin with some mediocre source (low level signal) and this mediocre low level signal source will be further amplified downstream and the overal end result will not be optimal.
You mentioned that currently you are using a cheap 10 year old Acam CD player and the Oppo 203 as your digital front end source components for your stereo music listening. While your 10 year old Arcam CD player or the Oppo 203 will be fine for budget setups and systems but since you will be purchasing some serious setup/system IMO your 10 year old Arcam CD player and your Oppo 203 will be the weakest link in the chain and will not be good enough for the kind of setup/system that you are considering to purchase. And as a result the entire setup/system will not be able to perform and sound optimally by using your 10 year old Arcam CD player or your Oppo 203 as your 2ch source of music.
Arcam makes very good AVR and AV processor but not CD player. Their CD players and DAC are mediocre quality.
I would highly consider upgrading your front end source component(s) first and foremost before upgrading your pre/amp or integrated and speakers. You can use the Oppo 203 as a bluray/4K UHD transport connected via HDMI to your new prospective AVR or AV processor for movie playbacks. Oppo makes great bluray/4K bluray players. Their video processings are very good.
There are countless options and choices to consider when upgrading from your 10 year old Arcam CD player, depending on your budget. The front end source component(s) are the most important equipment in hifi chain. IMO it isn’t worth getting high end expensive speakers, amp, etc if you’re only using some entry level or mediocre quality front end source component(s). The overall end result will not be optimal and you won’t be satisfied with the overall performance of your entire system setup.
When you visited a high end hifi audio show they are using very good front end source components in all high end setups and systems. Dealers also usually use very competent high end front end source components for their serious high end setups/systems.
They won’t be using the Oppo 203 or an Arcam CD player for some serious setups/systems costing $50k and up or $100k and up.
They will be out of place and the overall end sonic result will suffer tremendously.
