I have an issue with my new Rose 150 where I can hear a rapid “puttering” sound coming out of both speakers (97 db sensitivity.
I am able to reproduce this issue with 2 separate class D amps (Exposure 150 W and a VTV purifi tube buffered Class D @ 175w)
Interconnect cables, high quality power cords and all other swappable external components (including different AC outlets setup for hifi audio) have been tested and the rapid puttering sound still remains. It’s as if it’s clock running from inside the Rose.
