Sí, siempre dicen lo mismo de Marantz, concluyen así

They take the excellent platform used in Denon sister products, and modify them to produce objectively worse performance by good bit. Distortion is sharply increased and extremely slow DAC filtering causes lots of ultrasonic noise, making any intention of playing "high-res" audio moot. Company feels subjectively the modifications improve the sound of the unit. With no controlled listening test demonstrating that, and measurements showing the opposite, I don't think the changes are wise or merited.
Vamos, que cogen un producto excelente y lo estropean, porque son así, tontos. Yo esto perdóname pero lo cojo con pinzas
