Should I Sell My ARC REF 6 and Get A Pass Labs XP-32

So here's the question.  I love my ARC REF 6.  It's a great piece of equipment.  But  lately, I have been thinking that maybe I should switch from tubes to a Pass Labs XP-32, as I don't want to worry about replacing tubes in the future (like 5-10 years from now -- I know that there is plenty of stock now and I have a spare set anyway) as I approach retirement age.  Of course, other than buying a Pass Labs XP-32 and putting it into my system to see how it sounds, I am at the mercy of professional reviewers. The rest of my system: I have a Pass Labs 250.8 (so I think that there would be great synergy with the XP-32), MSB Discrete DAC with Premier Power Base and Wilson Sabrina X speakers, and a full loom of Shunyata cables.  Will the XP-32 be an improvement over the REF 6 for my system?  Should I sell the REF 6 and get an XP-32?
