About, "I acquired a Henry 2k-3 amp tabletop amp that works fine but the acoustic fan noise is so bad I have to keep it 20 feet away." I finally resorted to using a remote squirrel cage located in a small closet under the staircase. A plastic-type clothes dryer hose runs to the Titan II. Sweet (near) silence at last. And no vibration. 73, Roy K6XK/0
