What amplifiers/integrateds do you like with Cornwall IVs?


I sold my Forte IIIs and moved in Cornwall IVs.  I have 3 amps to play with, but because I'm doing break in and running them for long periods, I'm using a Class A Music Hall Mambo.  It sounds pretty sublime.   Later I'll try the 300B and PP KT150 integrated.  

What do folks like to pair Cornwall IVs with?  This Class A amp makes me think I should beg Santa for a Luxman Class A!

I might consider an Audio Note EL34 kit.  Loads of quality parts, single pair of el34 tubes, from what I have read quiet as a graveyard. Bet it would be a great match and a blast to build if you enjoy that type of thing.  They occasionally have sales to boot

Update--

So 30 hours of straight play from the Music Hall Class A Mambo, and I swapped in the Primaluna HP Integrated, running KT 150s and reissue Gold Lion 12au7s (I have enough NOS 12au7s to last 100 years, and I think these are almost comparable to NOS, almost).  

Holy cannoli!  This is nuts how holographic and gorgeous this sounds.  
Um, two words-- "Classical Music!"  ---I hear it like never before.  These speakers could be a doorway to and place within the genre for me. 
OP, I know you just swapped but can you pick a winner between the PL and the class A on the CW4? Seems like you really liked both.
