McIntosh MA 352 or C22 Mk V?

We recently put together a dedicated two channel system consisting of McIntosh MA252, Linn LP 12 TT, B&W 804 D3 speakers, Bluesound.  Our room is 15’ x 25’, with the listening portion in the front half, pool tale in the back half.  For 60-70% of our listening the MA252 (100 WPC) is good. There are times when I want to listen at higher volumes I am running out of power - tubes go from green to white.  I have two schools of thought.  Upgrade to a MA352.  I also own an older Levinson No. 333, that is in my home theater running my front channels.  I have considered pulling this out and adding a C22 Mk V preamp for the two channel system.   My concern is that I am living on borrowed time with the amp, as I know the caps will need to be replaced anytime and then I will either need to recap or upgrade the amp.  Thoughts?
