My experience is very consistent with this. I went from HDMI into an Onkyo SSP, which was very good. But then I went MCH analog into the analog bypass of the Onkyo and things got better. Then I upgraded the Onkyo to a dedicated MCH analog preamp, which was the next step up. Then I upgraded my MCH analog source to Marantz ud9004, which was the next level of improvement. To improve on a high grade analog signal path you need a very high grade SSP, which will probably end up costing you more.
The thing missing in this equation is room correction - which could be a big factor.
But bottom line, if you are getting limited room improvement mileage out of your anthem, it could be you are better off going analog than HDMI purely on the basis of sound quality.
If you have 3K to spend and you are willing to go down this path, I would scout out a used (or new discounted) marantz ud9004. Keep in mind, this player has downrezed SACD HDMI, so it is a big commitment to analog.
I would personally test the waters with an Oppo (which is an easy resale), and if you decidede to go analog you can get your upgraded, or get a higher grade MCH analog player like the Marantz.
