Das '''Design''' des Yamaha AX-570 wird durch die runden Auswahlschalter geprägt und hebt sich wohltuend von den sehr technisch wirkenden Varianten ab. Das Metallgehäuse ist solide konstruiert und die Materialien wirken sehr ansprechend. Der dezente Einsatz von kleinen Lichtpunkten zur Information runden den positiven optischen Gesamteindruck ab.

If you only clean the switches with contact spray you usually get problems again after a short time. You have to remove the contact spray from the switch/pot (e.g. with WL-spray), otherwise it will attack the contacts further. Afterwards the contacts are preserved e.g. with contact 61.

Notes[edit]




Sonically balanced analog push-pull transistor amplifier with elegant, simple look. Natural sound philosophy of Yamaha, best components and still a proper full phono preamp MM and MC.

The design of the Yamaha AX-570 is characterized by the round selection switches and stands out pleasantly from the very technical-looking variants. The metal housing is solidly constructed and the materials look very appealing. The discreet use of small light points for information round off the positive overall optical impression.
