CP-700/800 (or similar) w/ HT Bypass just for analog - Any point?

Guys- Looking for some advice here.

For about the last couple of years, I've been doing about 90% of my music listening through a vinyl front end (and loving it).  Recently I've been wondering if I'd be happier to get a dedicated 2CH analog Preamp simply to run my analog setup via HT bypass through my pre/pro.  

All my digital music at the moment is via HDMI (Apple TV Gen 3 and a universal disc player).

The reason that I'm considering the Classe is that I need the ability to run fully balanced/ differential with bi-amp capability but I'm open to others (Parasound, Emotiva etc.) but want to stay solid state.

Before I shell out thousands on a new preamp though, I wanted to know from those that have done something similar if the benefits are worth the expense.

My current setup is:

• Pro-ject 6-perspex w/ HOMC
  
• Schiit Mani phono pre (a sonic wonder for $129 once sorted)
  
• Onxyo PR-SC5509 pre/pro specifically purchased for the balanced connections and Burr Brown DACs)
  
• D-Sonic Magnum 7 channel amp
  
• Bowers and Wilkins Nautilus 800s (Biamped) front
  
• Bowers and Wilkins Nautilus 803s rear
  

BTW - When I'm playing vinyl, I keep the Pre/Pro in "pure audio" mode which Onkyo claims to completely bypass all processing (which I doubt is the case but is noticeably better than any other audio mode)

Other options I've considered / am considering:

• Scrap the Schiit in favor of a vastly superior phono stage, which I may end up doing either way.
  
• Scrap the 5509 and go with the Classe SSP-800 (which would obviously be a great match for my B&W setup)
  
• STFU and be happy with what I have and save the $$ and rack space :)
  

Open to any and all feedback and I don't really have any budget considerations.  Just want to make sure that before I take the leap that I won't be disappointed with a marginal (or no) step up in performance.  

Thanks very much in advance!
