Considering that you can currently purchase a new Rega Brio 3 for $500 (meaning that the used ones will now sell for $300, or so) keep the Brio 3 as a backup main amp and use it as a phono preamp while doing so.
If you switch from an AT pickup, to something else, down the line (or another deck ) then try the Roksan phono preamp again.
