Can I use an Integrated only as a preamp

I currently use 2 Adcom GFA 555II’s in bridged mode to drive my B&W 802 Series 80’s. I’m using an Adcom GFP565 as a preamp. I have been looking to upgrade the preamp with a new Adcom model, but a number of posters here have suggested (surprisingly) that an Adcom preamp is not a good match with their amps, (Thread 1171936986)

I also own a Sonic Frontiers SFP1 which I’m not using as it really isn’t powerful enough to drive the B&W’s effectively and so I would like to utilize it somehow as a preamp while retaining the power of the 555II’s.

Is this possible/ desirable and if so, how does one connect it?

Thanks for your help.
