As brother ghdprentice said, and speaking from extensive experience with a Luxman 550AXII, the word "sparkly" is an apt descriptor. The Lux offers a lot for the money, and I enjoyed that amp quite a bit. But ultimately decided to delegate solid state integrated chores to an Accuphase E-280, which I simply find more relaxing, less "hi-fi," warmer.less analytical, and easier to listen to. The one thing I wish the Accuphase had is a loudness control button on the remote.
Now if that isn’t a first world nitpicking, please tell me what is. :)
