Hi all,

I’ve got a similar case. I’ve a pair of Beolab 9’s (recently bought second hand) that are connected through a line-in on to a Yamaha WX-C50, using RCA to Powerlink DIN cables I purchased from Sounds Heavenly. The Yamaha works as the music centre receiving wired sources (optical and analog), ethernet (e.g. DNLA, or airplay) and bluetooth, and connects with multi-room linked Yamaha speakers located elsewhere in the apartment. The system works flawlessly and the sound is amazing. Overall, I’m a very happy person. 🙂

Nonetheless,
I noticed a slight hum when the speakers are on (when activated through the line-in signal detection). It’s not audible when sitting on the couch a few meters away, but noticeable when having my ear next to the tweeter. This is quite annoying because even without hearing the noise, knowing it’s there bugs me.

I was wondering whether this maybe due to the line-in connection is a tad sensitive to picking up random noise while a Powerlink cable allows for better signal processing? So I was looking for the cheapest way have the Beolabs connected through powerlink. The Beosound Core is an alternative to the Yamaha, but has fewer inputs than I want, and is twice as expensive. Would adding an Essence (MK1) in-between the Yamaha and the speakers solve the issue?

Or… am I overreacting, and is it perfectly normal to hear some activity in the tweeter when putting your ear next to it?

Thanks for your thoughts,

Thanks Steve,

I’m not doubting the quality of your cables in any way. It’s good to know that adding another device in between is unlikely to solve the (minor) issue, and part, if not all, is a known “feature”. So, I’ll not be spending money trying -and failing- to sort it. Thanks.

I will experiment with a different cable arrangement to see if that makes a difference. It’s admittedly a bit of spaghetti coming out of the back of Yamaha, and electricity cabling behind and under the cabinet.

Best wishes,

wnv
