Hello all I have recently become the owner of a pair of monster Jamo concert C809 standing speakers. I’ve always liked my hi fi separates but not up to date with the latest technology (catching up). My Rega Brio from 2001 isn’t up to the job driving these monsters. I borrowed a friends Arcam amp and the difference is like day and night. Does anyone have a decent amp knocking about gathering dust capable of driving these things? Not sure I can stretch to Naim prices. Let’s see. They have an extremely low frequency of 30hz therefore excellent bass. Have posted a link of an older review and spec. https://www.whathifi.com/jamo/c809-hcs3c80-sub/review
