I don't feel equipped to describe sound (mostly from lack of experience) but short of clapping two stones together and just declaring "me like!!!", I'll try. The impression I get listening to the Raptures is "solidity with finesse" meaning there is very solid and impactful bass foundation married to delicate defined treble information. Because I am very sensitive to a bright, harsh, edgy, irritating high end I will reject any cable or component that exhibits it. A system that possesses this quality, as mine does to a slight degree, demands an IC that does not accentuate it. However, this quality seems to be more software dependent in my system and while many excellent CDs are problem free in this regard, many more are IMO problematic. It would be great if a cable would attenuate this quality but then I suspect it would not be accurate in the treble.
I'm always hesitant to declare anything the "best" but I do believe the Rapture is the "best" IC I have had in my system. I don't feel that the Rapture is a "huge" improvement over the Revelation but I believe it possesses significant sonic benefits. Whether the benefits are worth the price difference between the Revelation and Rapture will vary with each system and owners priorities but for me, I believe the Raptures are priced fairly for the high level of performance they are capable of delivering, especially considering the prices of cables that would compete at this level. I would encourage anyone who is considering ICs in this price range or even significantly higher, to audition the GG Rapture. You may be very pleasantly surprised!
My most recent ICs were the Gabriel Gold, the GG Revelation and the Virtual Dynamics Revelation v.1, all balanced. Before those listed I used several highly regarded balanced silver cables which led me to the conclusion that I do not care for the sonic "signature" of silver.
Because I alternate between two CDPs that connect direct to my amp (EAR ACUTE and Wadia 270SE & 27i) I use only one set of ICs. The Wadias are connected with a VD Revelation Signature balanced digital cable and Aural Symphonics Optimism v.2 AT&T.
My speaker cables are bi-wire GG Revelations which replaced VD Revelation v.1 b-w which is a fine cable but extremely stiff and heavy. I was initially concerned about the gauge of the GG Revelation speaker cables being adequate but that concern has proven to be meaningless. All my PCs are VD Master v.3.
