I listened to that whole You-tube video and have come to the following conclusions:
- Separate AVP/or C are better, less jam-packed, not affected by the power amp section.
- AVR such as the RX-A3080 have internal amps that can be used for some less demanding "effect" channels.
So given that typically an "equivalent" AVR could be had just before or after the replacement model is out, for much less money that an AVP/C, one can do better in terms of value, without sacrificing sound quality.
In this case, the CX-A5200 could not even beat (in all likelihood) the RX-A3080 that is now available for under $1,500.
Reliability is an unknown, one would think the AVP/C would likely last longer but again, may be not, and the heat issue can be mitigated with a $10 quiet fan on slow speed.
If it is the WAF restriction, I would be very tempted to try out a RX-A3080 now.
