New ARC REF6se or buy a used ARC Reference 10?


I see that the ARC Reference 10 used, and the new REF6se are both around 17K. I haven't heard comments on a direct comparison of the two ARC preamps. There are obviously big advantages to a one box solution and having fewer tubes to replace. Has anyone heard this comparison or does anyone here have a strong opinion they would share with me?

If the Ref 10 is in excellent condition, it has advantages that the Ref 6se will not have. 
i too would buy the used ref 10 as long as it is really good shape with no issues
Well, thanks guys. I did just that. Bought a used REF 10. It will be replacing a rolled Rogue RP 7. I will let you know what it sounds like after I get it shipped here and heated up. Thanks for your thoughts!
