I have had both VD Revelations and Stereovox IC's in my system. The Stereovox was good, but the Revelations were better. I never did hear the Stereovox speaker cables. I got a Revelation Signature IC for my source (APL modded Denon 3910 player) and was so impressed I got a few more Revelation ICs, a power cable and also biwire Revelation speaker cables for my speakers (Legacy Whispers). The speaker cables replaced Audience AU24s, which had replaced Monster Sigma Retro Golds.
Soundstage deepened by about 20 feet on most material, imaging is excellent and there is more "presence/immediacy" to the sound. In other words, if you close your eyes, you are about 3rd row of the concert in your listening room. ALtho the macro-dynamics are impressive, the micro-dynamics are even more so, as I am hearing things on discs I haven't heard before. I know thats a well-worn cliche, but in my system now, it is true. Bass is lightening-quick and tight, mids are sweet and highs just sound "right". Simply put, there is just more "music" coming thru to my ears since I added Revelation wires and cables.
3 cautionary items if you decide on Revelation cables: 1- They are stiff, so I found it best to prebend them for the least amount of brain-damage; 2- They take a while to fully break-in. Altho they sound fine after 100 hours or so, they really shine after about 800, in fact, to a new level in my system, and 3- There is a definite synergy the more of these cables are in your system. I was skeptical, but it turned out be very true.
Hope this helps.
