Bought a set of Kef 2005.3 speakers yesterday and connected them to my Denon 500SD all in one system. This is temporary until I can find a Denon 1909 in stock and at a decent price! I've had the Denon 500sd for 4 years with no problems but want to upgrade having just bought a new TV and BluRay.
I've connected all of the satellite speakers, removed the speaker wire from the amps sub speaker terminal (old sub was passive) and used a single RCA from the amps sub pre out to the Kef Kube 2 left input. I set the sub volume to full and crossover to max as recommended in the Kef paperwork.
When I powered up the system and did a signal test it took a fair volume to get the sub to power from Red (standby?) to Green (active?) and once it was on I noticed a quite nasty hum!!
With the amp off and the sub still on green the hum is still present. I've tried powering the sub from the same block as the amp/tv/sky+/bluray and also from a separate socket but with no change. With it powered from another socket I can get rid of the hum by powering off the amp/tv/sky+/bluray socket but that's not exactly going to help!!
Has anybody else got this setup or experienced hum with the Kef 2005.3 speakers? Any thoughts would be appreciated.
