Musical Fidelity A-Series: which is the best of this group?


Hi folks,

Regarding Musical Fidelity’s A-Series integrated amplifiers, which is the best of the list below for being laid-back, smooth, warm and/or “tubelike” as I have seen written on more than one occasion? Of those, which has the best imaging and soundstage as well? 
I’m running Vandy 2CE Signature speakers with an Arcam irDac and Cambridge CXC transport. I’m coming off Krell and Naim gear which was better mated to my old Vandy 2C’s, which were more laid-back and slightly bloomy in the bass. The 2CE’s I have now are much better balanced and detailed in the bass, as well as having more presence in the mids and highs. They don’t mate well with the full, forward sound of Krell or Naim. Does anyone have any experience with all the models below that can give a comparison? 
Musical Fidelity Integrated Amps I am considering: 
A300
A3
A3.2
A3.5
A5

Something new to consider (it was reviewed using your speakers).

Of the first 3 MF's on your list the A300 was smoother (not familiar with later models).

I have the A-300 and it is my absolute favorite power amp of all time. A true KEEPER.Incredible power, absolute finesse. Drives my Maggie SMGa's with sublime accuracy.
My utterly biased opinion is A300 because it is a much bigger number. Also I am assuming I knew what I was doing when I bought one 20 years ago to pair with some Dynaudio floorstanders aiming for neutral. I think at least some of those other models were available at the same time. I bought my first tube amp this year, but I still have the A300 in the rack. I swap speaker cables to it some nights. It holds up pretty well considering the tube amp was more than 2x the price.
