McIn­tosh has re­leased what it says is its first-ever hy­brid in­te­grated am­pli­fier. The new McIn­tosh MA252 uses two 12AX7a and two 12AT7 valves in its pream­pli­fier stage and high-power out­put tran­sis­tors in its out­put stage. It is rated to de­liver 100-watts per chan­nel into 8 loads and 160-watts per chan­nel into 4 loads.

Un­like many re­cent am­pli­fier de­signs, which fea­ture in­te­grated DACs, the MA252 is all-ana­log with two un­bal­anced line-level in­puts, one balanced in­put and a phono in­put (MM), all of which can be ad­justed for off­set level to en­sure con­sis­tent vol­ume when switch­ing from one in­put to an­other. ‘ McIn­tosh has taken a de­sign lead from the leg­endary MC275 to pro­duce an in­te­grated am­pli­fier that in­cor­po­rates the best of both the solid state and vac­uum tube worlds,’ said Philip Sawyer, of Syn­ergy Au­dioVisual, which dis­trib­utes McIn­tosh in Aus­tralia. ‘ To re­lease a 100-watt am­pli­fier that is com­pletely hand made in the USA at this price point is won­der­ful.’

The high-cur­rent tran­sis­tors in the out­put cir­cuitry are mon­i­tored by McIn­tosh’s patented ‘Power Guard’ cir­cuitry which mon­i­tors the out­put sig­nal for signs of over­driv­ing and makes real time mi­cro ad­just­ments to the in­put sig­nal to pre­vent harsh-sound­ing clip­ping that could po­ten­tially dam­age your speak­ers.

The MA252 has a sep­a­rate head­phone am­pli­fier and all set­tings and in­put se­lec­tions are shown on the front-panel OLED dis­play. Avail­able now the McIn­tosh MA252 sells for $6,995 (RRP).
