luxman or arcam preamps will be much warmer than rotel which
can sound overly lively and bright like there is oil in the sound,i still like it in certain setups it's very fast and sounds nice like grado headphones very open and sweet.
iv'e auditioned a nad c352 after owning arcam and rotel integrated amps,the nad is too polite. iv'e ended up with ifi itube as a tube preamp, arcam delta 120 power amp. so id'e recommend the ifi itube 2 350$
