Installing Stealth Indra between the source components and linestages significantly reduced background noise to the quietest level I've yet to experience. There is a "liquidity" to all music that doesn't appear with other interconnects when Indra is placed in the signal path. The articulation and delineation of information is greatly increased along with the speed of the music. Replacing Indra with any other interconnect tends to "slow down" the music as well as reduce the dimensionality of the presentation. Music appears to flow from the speakers as opposed to being projected from them. There are not enough superlatives to describe Indra; they simply must be heard and not just for 1,2, or even 7 days. It really takes a number of weeks, many listening hours, and different source recordings to fully appreciate their contribution (which ironically is nothing) to the system. However, they will reveal any weak link(s) in the system.


"Formal" listening test

In January 2004, five listeners (four friends and I)  spent 10 hours over a weekend performing blind auditions using Indra, Compass Lake, Valhalla, Pursang, Dream Dancer, and Dominus. The arrangements were such that each person would install 2 pairs of interconnects unknown to the other members. We then listened to the following:

1. Café Blue, Patricia Barber compact disc

2. Brandenburg Concertos, Boston Baroque Orchestra Telarc compact disc

3. Waves The Bossa Nova Sessions, Eden Atwood 180 gram vinyl

4. Body Acoustic, David Chesky compact disc

5. Brother in Arms, Dire Straits 200 gram vinyl

6. Dark Side of the Moon, Pink Floyd 30th Anniversary 180 gram vinyl

7. Waltz for Debbie, Bill Evans Trio compact disc

8. Gone Like a Train, Bill Frisell compact disc

Passages were selected by the 4 listeners who were unaware of the interconnect pairings.

The listening continued through the weekend until each interconnect had been paired against every other interconnect at least twice. We then took an additional 4 hours comparing our listening notes and compiling results. For each listening comparison an interconnect could receive an arbitrary maximum of 5 points and a minimum of 1 point. The results were as follows:


Compass Lake

Dream Dancer




Indra placed first with 4 listeners and second with 1.

Compass Lake placed first with 1 listener and second with 3.

Dream Dancer placed second with 1.
