You will not find tape loops any more. A few receivers may have a tape out, but it will only send a signal form analog sources and NOT digital ones. This is for reasons of DRM.
Also DSD decoders are not common and the multi channel analog inputs have pretty much gone by the wayside. So the most common situation is now sending PCM from the SACD player over HDMI.
What are your speakers. I think that really decides the issue of whether to recommend a good pre/pro and external amps, or your proposed solution.
The receivers to look at are Denon, Marantz and Yamaha. I would give the others a miss.
There is the really
only receiver that comes close to your wish list. The only thing lacking, is the tape monitor loop, which you will not find anywhere, and a DSD decoder. I doubt you will find that any longer. This is the only receiver that meets most of your specs, and has multi channel audio inputs for your SACD player.
You can save money by getting rid of the phono input and using and external phono preamp, and dispensing with the 7.1 analog inputs. In the latter case you would have to have the CD player send the audio as PCM over HDMI.
Unfortunately for you your request list is not easy to full fill.
