Roksan Platinum ST-1308 Stereo Power Amplifier
The Platinum Stereo Power Amplifier simultaneously delivers a deeper, tighter wholly controlled bass with a realistic open mid range and detailed, extended top end. Fully symmetrical, complimentary circuit design and use of superior quality components throughout ensure optimum amplification of the signal. A substantial, quadruple power supply design and ultra low output impedance with constant power response allow this amplifier to deliver its full dynamic potential into almost any loudspeaker presenting a wide bandwidth and grip with negligible distortion. There are as many as 4 Toroidal transformers to provide optimum power delivery with full isolation between the main amplifier circuit and the input control, logic circuit and signal switching relay power. Precision timing and enhanced sound staging are hallmarks of this world class power amplifier.
