NAP150x with NAC102 or something better to drive Linn Majik 140

Dear forum members,

Having had multiple Naim components with variety of speakers during my long hifi journey (well more than 20 years, up, but still kickin') I've stuck into having above mentioned speakers, which not seem to perform well as they can with my current Bel Canto S300 amplifier and one passive preamp in chain (Luminous audio technology Axiom II). I have an opportunity to buy NAP150x with NAC102 preamplifier (or maybe NAC112x, although I have had 112x as well as 122x, and being happy only with 2nd), so I'm wondering if some of admirable Naim forum members can help me with this. Is it better off buying something stronger from the start  or stick to 150x and later maybe improve preamp (I've used to have 122x/150x combo with my previous Harbeth SHL5 speakers and Living Voice, too, and it performed fantastic to my ears, really)? Or go to other parallel routefrom the start (Linn)? I have to admit that I prefer staying in the Naim playground but listening to Majik has proven to be the best choice option for my room, which is of considerable size 4 x 8 m that prolongs to other parts of the apartment.  

Unfortunately, no speaker change is possible right now, because I have already chosen these. Listening to very modest up to moderate levels.

Thanks in advance for support
