Hello,

I am using a Resolution Audio Opus-21 CD player with a Naim NAC-82 preamp.

I am connecting it via the CD phono output [which passes through the analog volume control in the CD player].

I have read that I can improve things if I use the CD din output [which does not pass throght the CD player volume control] and I contacted Rresolution Audio about this. They confirmed this arrangement should give better sound and they recommened a cable made by DNM.

I have checked with DNM and they make two suitable cables one costing £70 and the other £250 [approx].

The difference is the use of

http://www.dnm.co.uk/hftns.html

which is a high frequency termination network which works as follows ..

"....
The DNM HFTN is a precision circuit fitted at each end of the cable. It levels severe impedance dips and peaks in the cable whilst remaining absolutely transparent to audio signal. The amplifier-to-cable interface is therefore improved by the HFTN, giving more audio clarity, greater image depth and delicacy of sound.
The sound quality improvement with digital signal sources is substantial.
..."

Does any one have any experience of these cables ? In particular has anyone any experience of the DNM HFTN.

Thanks

James

Looks like a rc network to act as a high pass filter. You'd have to find out what the output impedance of the cd player is through the din connection - it might be in the booklet or on their website.

The other thing..... I thought that naim amps were already bandwidth limited - but you'd need to check that one out. If your amp is, then essentially it already has the network inside.

Interesting angle for them to come up with.
