I have numerous true balanced pieces. I have found without exception that they sound best using balanced cables instead of single-ended. Case in point: BAT. I have the VK50SE preamp and the D5SE CD. Another case in point, Levinson, both the 333 and 33H. All of these components came to life with noticeable improvement in sound with balanced use. Don't even consider BAT unless you run fully balanced. Your mileage may vary!
