With the quality and directness of the CD-5/integrated combo you will have a plethora of options, many very good. I have written about the Wireworld and MIT brands in conjunction with Ayon players. I also reviewed the CD-5 and am using it now as my reference Redbook player.
I have also been running several CD-5 to amp/integrated options for a while now. You can see one such option in my Audio Blast article about the modest overachieving Peachtree Audio Nova. With the Gain feature of the CD-5 this integrated performs very admirably. However, if you own the CD-5 you know about the Gain feature already. You have used it, haven't you? If not, you need to read your manual and learn what it can do. If you haven't used it yet you're missing out on a large portion of what the CD-5 can do - and what equipment can be paired with it successfully.
What Integrated are you using? This may have a bearing on the cabling selection. I certainly would want to know that prior to concluding which cable would be preferable.
There are other considerations which should be taken into account, and other options which can be implemented having huge impact on the results. I discuss such things in my reviews of cables.
For instance, I would not simply consider the Interconnect as an independent choice, but only in connection with the other cabling in use. It is rather a hit or miss proposition to slap an IC into a system when the other cabling is not used in a systematic way to attain the optimum results. One can certainly do so, but it's not the best way to get premium sound.
Now, this being a second rig, you simply may not care. But the CD-5 is such a good performer that you should care. Putting the "wrong" cable into the rig will seriously restrict performance. It literally can be the difference between sensational and nice sound.
I would be interested in knowing the geometry and total gauge of the Gabriel Gold cables. I did not see any info on their site. Is this revealed in their literature? Anyone care to share?
