New McIntosh MA252

I'm looking at this amp as I'm thinking of reconfiguring my audio listening room. I have ZU omen Defs. I've been going back and forth on various forums about amps to go with my PS Audio BHK preamp. I was considering a hybrid BHK250. Benchmark AHB2, Quicksilvers, MC275, etc.

However, chatting with someone who asked why not go with the Macintosh Hybrid integrated for $3600? 100 wpc is more than enough. It has a sub out (I use subs with my zus), remote and tube preamp. 

I could almost even trade my BHK for the entire unit. This might be something to think about

I am planning to get a Sonus Faber Serafino. Currently using Primaluna prologue premium with martin logan bookshelf. 

I listen mostly to classical, Jazz and lots of vocal. I have enjoyed so far with Primaluna tubes but can't use it for the Sonus Faber Serafino. 

Will McIntosh MA252 be sufficient enough to drive the Serafino or should i get MA352? Will i get the warmth of the tubes in MA352?

Has anyone compared the MA252 to the Audio Research VSi75? Both are on my shopping list but cannot audition as I live on Vancouver Island.

I have listened to the MA 252 in two systems and I would strongly lean toward it if in the market for an integrated

Sounds good with my JBL 4312 SE

I owned a MA6500 two years ago and loved it, btw, the 6500 is rated at 120 watts (8 ohms) It was the MA6900 that is 200 watts. The 252 is rated at 100 watts 8 ohm but to me sounds more robust than the 6500. Plus the soundstage and depth of the 252 is superior.
Loved the 6500, love the 252 more.
