I get fine results with my Luxman 507U. Kind of a Goldilocks sound, not too boomy or bright or etched, lots of character, sweet palpable rounded vocals, nice all-there highs that are not painful. Almost on the level of the Pass X350 power amp I once owned, and bass is better defined on the Luxman. The Pass had a bit more roundness to vocals and depth. Using a good tube preamp with the Luxman as a power amp really makes things shine.
