Adcom GFP-710 to Schiit Freya - upgrade?


looking for some thoughts...

It’s been a while since I’ve done anything with my system. I’ve been running a Mac Mini streaming AIFF via Kimber USB into Bel Canto
Dac-3, running the DAC into Pass Labs X250.5 via balanced BlueJeans XLRs. Speakers are Dynaudio S5.4
I recently added a Rega P2 table and that forced me to break out the Adcom GFP-710 that I had laying around in order to be able to switch between sources. Adcom has a built in phono pre, but I bought Schiit Mani as well. I kind of like it a lot. 
I feel that the Adcom may be the weakest link in the chain, and am looking at possibly upgrading a pre. 
Seeking thoughts on Schiit Freya, or any other preamp used or new around $1k that would offer an upgrade in resolution, soundstaging, imaging, etc. 
Balanced or single ended, tubes or solid state, with or without a built in phono pre.

Has anyone compared the Freya to any of the Adcom or comparable preamps, what can you share? What other preamps should I put on a list?

I left out the best part...a hand made little Dennis Had Inspire "Firebottle HO" single ended 12wpc tube amp.
Update on my preamp situation...

So after all the research, I pulled a trigger on a used Rogue RP-1.

It’s been in my system since yesterday. Need to do some more listening prior to concluding whether or not it’s a good fit.
