PS Audio M700's with which preamp?


Putting this out there for some feedback-
i recently upgraded my outlaw system- an older RR2250 receiver with Outlaw M200 mono blocks driving Focal chorus series 836V speakers.
i have an mid-entry Pro-ject turntable upgraded with a Dynavector 10x5. For digital, I have a Marantz network audio player- NA8005.  I have never been thrilled with the sound staging.  So I replaced the outlaw mono blocks with PS Audio M700's.
It's better, but not great.  
Heres the Q: would replacing the outlaw receiver as preamp (to what?) would make BIGGEST improvement to sound stage and imaging.
should I just go with the PS Audio Gain Cell?
thoughts? Is there a clever pre-amp selection (under $3K) that would add some magic?
thanks!

Remember that Class D digital amps require a prolonged break in.  Expect 200-300hrs on those amps before they start to open up. 
You haven't mentioned what cabling you are using? 
Honestly positioning your speakers could also change everything. 
Did you keep the m700s.  Curious as I have the outlaw mono and was looking at upgrading ps audio or parasound.  I'm expecting a big difference but it doesn't sound like it is?  

Thanks
I ran the M700s with an Aethetix Calypso with fantastic results. I just last week went back to my Modwright integrated for a change of pace, still has great tone and response but sound stage has shrunk, I will be moving back soon.
I had the Stellar GC at the same time as the M700s. The preamp lacked body and soul.


Do not stack the amps. Power cords make a huge difference. WireWorld Electra 7s are excellent and reasonably priced. Now using them throughout
