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,
