Digital Cables: Optical, Coax, BNC, or a simple RCA interconnect?


Until recently I've been using a WireWorld Optical cable (~$100) which I bought when I was using a Pioneer PD 65 CD player as a transport (until it died) and optical was the only out option. So, I've been using my Oppo 105 to play both SACDs direct via XLRs to my Audio Alchemy DDP-1 dac/pre and recently using the optical cable for redbook playback.

Last week I was reading up on Coax, and one thread suggested trying a regular RCA interconnect, although the connectors are not 75ohms. I had a pair of DHLabs BL-1 (older light blue jacket) laying around and decided to compare it to the optical. Easy Peasy as the DDP-1 has various input connections which can be accessed on the remote. Well, amazing doesn't come close to how much the music became alive/tactile/3D.
So, I looked on DHLabs site after reading that their D-750 was highly regarded. They will let me return it if Im not satisfied. That's the good news, but a 1.0m cable is $150, certainly not expensive, but Pangea makes one that seems extremely well thought out and it's on sale at Audio Advisor for $49.95 plus free shipping, so I ordered it. Depending on how much it blows me away I may go ahead and order the DHLabs too, just to compare
Anybody have anything to contribute?

Thanks. I checked, it's ~ a 12 YO design. I wouldn't think it would compare to newer designs/materials
I replaced the 1.5m Pangea with the 1.5m Pangea XL a couple hours ago. Obviously 'some' break in is needed, but, in short, the presentation is much more intimate. I find my body grooving to the Paul Butterfield Blues Band "Better Days"
As previously mentioned, I replaced the 1.5m Pangea Premier SE with the 1.5m Pangea XL, the presentation is much more intimate. I find my body grooving to the music: PRAT. Now, some 50 hours of play time later, I am blown away (especially for $150!). So far, every redbook CD I played I am much much closer to the actual recording: singers and instruments are extremely palpable and when recorded, bass, drums, and piano are very authoritative.
