Luxman's status at the pinnacle of high-end audio. In these latest integrated models, the gorgeous texture and three-dimensional performance of our original Class A amplifiers has been retained and further refined. For example, the L-550A II amplifiers featured a new electronic selector switch, adopted from the input section of the C-1000f control amplifier; while the L-550Ax series now uses a variation of the LECUA discrete volume control first introduced in the C-1000f.
Chassis bases have superb vibration absorption in order to supress noise levels. The power transformer, electrolytic capacitors and amplifier output stage are laid out so as not to interfere with each other. To reduce interference further, the block construction isolates each section using shielding panels, and extensive internal filtering to reject magnetic flux interference.
