The L-505 series that has captivated many music fans as a most affordable high-class amplifier was reborn to a much-awaited ultimate edition. The feedback circuit, ODNF, which is vital to sound excellence, was upgraded to the latest version of the high-class specifications. L-505u has again incorporated a pre/power separation switch to adapt many system environments, high-quality sound input selector IC that has been used in our flagship model, C-1000f, and more. The champagne gold color (limited edition) is also available to harmonize with conventional models. The music essence has proceeded to the higher level along with sufficient power of 100W + 100W (8Ω).
