Review: Revelation Audio Labs Testament, Paradise, Precept Speaker cable

Category: Cables



Revelation Audio Labs: A System View

I would like to share my experiences with the Revelation Audio Labs cables including their Precept power cables, Paradise RCA and XLR interconnects, Paradise phono cable, and Testament speaker cables.

My first exposure to Revelation Audio Labs began with the purchase of a Precept AC cable in December of last year. I wrote a review of this cable and compared it to two other well-known and respected AC cables.

This was the finest AC cable I had ever heard due to its revealing midrange; great speed and power in the bass, and a detailed, but non-fatiguing high end.

Three months latter, I purchased a Graham Phantom tonearm and decided to replace the Graham IC 70 cable I was using with a RAL Paradise phono cable.

Here are the results of that experience:

I was so impressed with the phono cable, that I ordered speaker and interconnect cables from Brad at Revelation Audio Labs. I am using two sets of XLR interconnects and one RCA set that runs from my preamp to my Wilson Watchdog subwoofer. I was using Silversmith Silver speaker cables and Cardas Golden Reference XLR interconnects.
Compared to the Silversmith Silver speaker cables, the Testament speaker cables were faster with far greater resolution from low to high. High-end details were simply something else; a Martin guitar sounded like a Martin; a Gibson mandolin sounded like a Gibson. On the other hand, the Silversmith speaker cables were slower and darker in comparison. Most of all, the dynamic qualities of the Testament speaker cables were simply the best I have ever heard. The Testament bass was very fast and defined with great power and slam.

The Cardas cables have been reviewed by a number of Audio sites recently, but the most accurate review in my opinion was that of Robert H. Levi of Positive Feedback Online:

The Paradise cables were faster with a greater sense of blackness to the background than the Cardas. The bass was not as prominent, but more detailed. The highs were also more detailed and had a greater sense of ease or speed, but were less prominent than the Cardas Golden Reference. Both cables had a wide and deep soundstage.

In summary, I heard the same qualities in the speaker and interconnect cables that I heard in the Precept AC cables. I did notice a synergistic effect when all the cables were Revelation Audio Labs. The first thing that struck me was the degree of enhancement of background silence. Very small details emerged from this silence that was previously obscured by the other cables. The natural beautiful midrange of the RAL was enhanced and had almost a “tube-like” midrange quality. The third enhancement was to the soundstage width and depth. It became huge. Two other audio enthusiasts have e-mailed me their impressions of RAL cables. The common thread that seems to run in everyone’s impression is the uncolored and engaging quality to the midrange most often described as “musical”.

Given the cost of high end cables today, the Revelation Audio Labs cables are truly a bargain.

Soundwise, I find them an improvement on my old Tara Air 1 cables. They have greater extension and air than the Taras. I felt I had removed something from my system, not added it--there was less "speaker cable" there. Of special interest is the more full and defined bass. I have had poor luck with silver cables in the bass and I felt I might need to go back to the Taras if the Testaments did not measure up in that area. Some discussion with other audiophiles leads me to believe that the less satisfying bass found in many silver cables is due to the makers using too thin a gauge of wire. This is often suggested as the reason for the perceived brighter highs, as well. Perhaps simply using a beefier gauge of silver wire is Brad's secret---I don't know! In any case, I'm pleased.
While the B&W802D is not considered a bright speaker, I did not hear any of the signs of "silver brightness" at all. (Frankly, I consider the whole "silver brightness" issue to be wildly overrated. Either that, or it's one of those things that some people are oversensitive to.)
I also note that while the Taras were very sensitive to outside interference (they really had to be up on cable elevators and dressed away from the steel stand) the Testaments seem, to my ears at least, to be pretty much immune. Again, this is impressive and speaks well to the effectiveness of his shielding technique.
Overall, I'm very happy with the biwire pair and consider them one of that rare species, the genuine audiophile bargain.
The Taras have since been sold via Audiogon. (^_^)

I bought the RAL umbilical for my Musical Fidelity Nu Vista and was very guarded as I abhor the silvery sound. Brad assured me that they were smooth with no top end etchiness. How right he was. I then tried the interconnect. Still no etchiness. If anything the top is full of wonderfully sheeny. The midrange is tubey with voices in the room and the bass absolutely natural. They have elevated my system to anotherlevel and I have now ordered the PSU cables for the amplifier and Precept II for both my amplifier and CDP.
The interconnect is the best I have heard and have used Nordost SPM, Acoustic Zen Golden Reference, Chord Signature and most recently Chord Indigo ($2000) which is recognised as the best interconnect made in the UK. Well done RAL

On Dec. 21, I paid Brad for an HDMI cable, based on his email stating "I am pleased to inform you that I will have your custom 2-ft. length at your door by week’s end…"
Here I am three weeks later, and no cable, no contact about the status, and now he does not respond to email or telephone calls.
IMHO he is a liar and a thief, despite his claim be be a Christian.
I suggest that you not buy from Revelation Audio labs, or perhaps offer him a 20% down payment with the remainder on delivery.
