L'amplificatore integrato MA252 è il primo amplificatore integrato ibrido di McIntosh. Prendendo spunto dal design retrò dal leggendario amplificatore valvolare McIntosh MC275, il MA252 combina il meglio del design dei circuiti a valvole e a stato solido per creare un amplificatore che è sia visivamente che sonoramente sbalorditivo.
