Reducing impact of rLink DAC's power supply

Posted by: Gavin B on 15 August 2014

I've just acquired an Arcam rLink DAC to sit in between my 252 and Denon DNP F109 network player.  I'm hoping that this will improve the slight muffled characteristic of the Denon sound.

 

I'm conscious of the potential impact of plugging the DAC's power supply into my power block.  Is there anything I can do to minimise this?  I have some chunky ferrite cores that came with my TV - how should I use them (given the diameter is larger than the DAC power cable).

 

Thanks

+1 to add ferrite to a SMPS DC lead

 

Wrap the DC lead around the ferrite as many times as you can, I have most with 4 turns = 5 passes. Wrapping thru a ferrite increases the ferrite noise attenuation & lowers the peak effective frequency a little over a single pass.

Thanks, Mike, I'll give that a go

Gavin, I'm also a great believer in ferrites (as Mike knows).  I would also suggest putting a ferrite on the mains side cable (either the SMPS lead itself if it has one, or on an extension lead) as SMPS can also emit RFI back down the mains.
