老厂同样也会有令人注目的新作。在Hi-Fi市场十分疲软之时，美国知名品牌McIntosh陆续推出了几款新作，包括MC501后级、C200前级，还有XRT28音箱，且都是顶级制作，让人对这家老厂不得不刮目相看。
其中，MC501为一款重型功率放大器，该机功率为单声道500W输出，采用了全平衡推挽式放大电路，并使用了超宽频多线并绕式输出变压器（这是麦景图的一种具有鲜明特色的变压器技术）。该机外观与传统麦景图放大器的风格十分相似，但在面板设计上颇有新意的采用了3D立体玻璃，并采用了LED光纤照明显示功率表头，令MC501外型更加生动。
由于麦景图多年放大器开发经验的积累，加上500W的强大功率输出，MC-501具有超强的推动与控制能力及动态强大的声音表现，而且声音温暖、饱满，是Hi-End级发烧友值得关注的一个目标。
