Should I replace my Conrad Johnson PV-2 with a McIntosh C-28

Have a chance to buy a Mcintosh C-28 preamp at a good price in excellent condition.  Current set up is Conrad Johnson PV-2 to go with two McIntosh MC2100 as monoblocks driving a pair of Dahlquist dq-10 and a McIntosh MC2105 driving two JBL L100s.  Play mostly vinyl.  Like tubes better, but I will admit it - I am a sucker for the look of the Mcintosh. 

Wondering if anyone out there thinks the C-28 is an upgrade over PV-2?  (dont want to buy it just to try it).  My heart says YES, but my head tells me it will be another piece of gear in my current graveyard of unused gear and I will go back to the CJ.
