phono stage Herron or Pass?

I'm looking at either the Herron 2a or the Pass XP-17.
It seems most people have heard one or the other.
Anybody heard both and have any preference?
I have a Herron pre and a Pass Amp.
Thank you for any opinions.
I haven’t heard the Pass phono but I do have the Herron 2a and 360 feeding a Pass Xa-25.  If you are looking for neutral I can recommend the 2a.  The 360 imparts a tube sound so makes a great pairing.  
Also running a 2a with the Herron linestage—phenomenal combination. Using LTA amplification.
