sub 2k phono stage

I am running a moving magnet into a sonic frontiers pre-1 P tube preamp - using the phono stage only via the tape outs into a passive preamp.  The question I have is whether a newer stand alone phono stage such as those offered by rogue, etc- new or used - would best an older unit such as this.  For those of you who are not familiar with it I believe it is on par with an audible illusions.
