German manufacturer AVM Audio has introduced two new phono preamplifiers in its Evolution series – the PH 3.3 and PH 5.3 – designed to work with a wide range of MM and MC cartridges. The main difference between the two models lies in the output stage: the PH 3.3 uses a low-noise transistor-based design, while the PH 5.3 features AVM’s proprietary tube output stage. According to the manufacturer, the tubes used in the flagship model are rated for a service life of several tens of thousands of hours.
