 What Hi-Fi?: “How does this combo sound? In a word, wonderful...

This amp set is fast insightful and bombastic, delivering the likes of the White Stripes with an enthusiasm that's rare at any price...

With their ultra-vivid and transparent midrange, sky-high build quality, good connectivity, and one of the most pleasing metal remotes we've seen, these Roksans are masterclass of amp design”.

Platinum ST1308 Stereo Power Amplifier

Platinum RangeThe 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.

Platinum RangeThere 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.
