To test Granite Audio's interconnect, I connected it to a CD player and an integrated amplifier. Immediate impression: It is one of a few pure silver high-quality cables the performance of which satisfies me. The cable will be available on the world market for US$600 per 0.5m pair.

Geometry

I found the Granite Audio No. 470 neutral and natural. Dave Grusin's album sounded just the way I like it. The bass was deep and under control. The space and detail of Scott Henderson's compositions were just great. I would be a fool to expect any better from my midline system. The flute of "Fascinating Rhythm" was truly reproduced. I always play this number when I'm testing devices, many of which have failed.

The piano sounds as it should. The clarinet in "Prelude" was another proof of the No. 470's quality. Dave Weckl's percussion instruments can be compared to a cherry on top of cream. Grusin's album was marvelously reproduced, full of body and soul. Even the tiniest cymbal sound was fascinating. I played John Pattifuccie's "How Long Has This Been Going on" to test the double bass. Again, superb. By the way, John Pattitucci and Brian Bromberg are my favorite double bass players. It's a shame that I have only one of Brian's solo albums. Vibrato and various string buzzing sounded authentic, likewise vibraphone and percussion. To judge the sound of the deepest double bass, I played Bob James' "Playin' Hooky," a good exercise for the loudspeakers. The deep bass was faithfully controlled. The trumpets sound lovely in the duet with vibraphone.

The Suk Chamber Orchestra's performance of J.S. Bach's Concerto for violin, oboe, string orchestra and continuo, BWV 1060, emphasized the Granite strongest qualities. I further concentrated on the Adagio, where the oboe has a chat with the violin, with the rest of the ensemble doing fine on the background. The violin and strings in the Alessandro Marcello's Concerto for Oboe sounded marvelous. I ended up sitting back and putting off the search for subtle distinctions and immersed myself in the beautiful, sad melody.

Finally, I tested Tuck Andress's guitar. His fascinating technique is admirable. This super dynamic record from Windham Hill helped me to distinguish the smallest differences in sound. How did Granite Audio cope with Tuck's guitar? No problem!
