    I like the look (and sound) of the CJ more anyway.
    Who did the testing to determine the plastic cover sounds better than the metal cover?

    Actually ARC did and mentioned by another well known reviewer here.

    "The review sample's top plate was of tinted polycarbonate, with slot vents. A cover of perforated aluminum is also available, but ARC recommends the polycarbonate, perhaps because of lower chassis resonances."

    "The remainder of the chassis is black-anodized aluminum, with a cover of transparent polycarbonate polymer, slotted for ventilation. While the top can still be ordered in traditional aluminum, go with the acrylic -- it not only provides a bird’s-eye view of the interior, but, per ARC, it sounds better, presumably due to its antiresonant quality."

    Shall I go on?

    Did you ever bother to compare the covers in any of your reviews?

    Hello everyone. I finally received my GAT2 fresh from the factory. I swapped out my XLR cables for RCA connections and I’m getting a a loud static/hum. Any ideas.

    Please make sure that your RCA cables are properly seated. Push them all the way in and if they are locking connectors/barrels (which I don't like), make sure they are fully cinched up and tight. But not so tight that you can not get them off. Check both amp and preamp.

    Congratulations on the GAT2.

    Since he never answered the question about the amp he is using he may be using XLR to SE cables and if so have a ground loop which may require lifting the ground on one of the two pieces or running a grounding wire between them.
